2017-11-11SDL: Fix assertion when using 4bpp cursors with a key colorBastien Bouclet
Myst ME uses such cursors.
2017-11-11SDL: Use RLE acceleration for SDL2 transparent surfacesThierry Crozat
We were already doing it for SDL1.2, but with SDL2 the SDL_RLEACCEL is not passed to SDL and instead we need to call SDL_SetSurfaceRLE.
2017-11-11SDL: Preserve mouse position when switching between OpenGL and SurfaceSDL ↵Thierry Crozat
backends Since those GraphcisManager initialize the cursor position to (0,0) when created the cursor was jumping to the top left corner and then moving back to its initial position as soon as the mouse was moved. Now it stays at its initial position. There are still some issues with it when changing between OpenGL and SurfaceSDL at the same time as toggling fullscreen. But it is not worse than before.
2017-11-11SDL: Fix display artefacts with transparent OSD messageThierry Crozat
If we do not update the area below the message, it is just blitted on top of itself again and again and gets progressively less transparent. It also causes artefacts when the mouse pass below the OSD message.
2017-11-10SDL: fix various OSD message artifactsPatrik Dahlstrom
On the OpenPandora handheld, the OSD message would not render unless you moved the cursor in the area where it was supposed to show. Additionally, the OSD message was not transparent like in v1.8. This commit fixes both these issues.
2017-11-07SDL: Get correct default graphics mode ID when queriedColin Snover
Fixes Trac#10312.
2017-11-07LINUX: Fix Header for major/minor macros, thus removing warnings.D G Turner
Warnings are as follows: "In the GNU C Library, "minor" is defined by <sys/sysmacros.h>. For historical compatibility, it is currently defined by <sys/types.h> as well, but we plan toremove this soon. To use "minor", include <sys/sysmacros.h> directly. If you did not intend to use a system-defined macro "minor", you should undefine it after including <sys/types.h>"
2017-10-23SDL: Automatically grab mouse upon entering fullscreenColin Snover
Folks are confused about the new behaviour where the mouse is not restricted to the game area in fullscreen, which is understandable. This changes mouseIsGrabbed to use SDL directly in order to avoid making changes to the user preference in the _inputGrabState. Otherwise we'd either clobber the user's previous windowed mouse grab preference, or require maintaining a second variable just to track the original state, when we can have SDL do that for us.
2017-10-19SDL: Fix SDL1 cursor position when using a touchscreenTarek Soliman
I noticed that in Maemo the cursor was offset after the SDL refactoring in de2bbe3b9738ef95b2529db989570770ef434f9d In Maemo when entering fullscreen, ScummVM receives a SDL_VIDEORESIZE event with the native touchscreen resolution rather than the current window size. This causes a call to notifyResize. Before that refactoring, notifyResize did nothing (in SDL1). Now it calls handleResize but doesn't actually set a new video mode. This messes up the coordinate mapping, causing an overcorrection for the cursor position.
2017-10-17SDL: Fix missing scaled cursors in SDL 2.0.4 on WindowsColin Snover
This may be a problem with SDL 2.0.4 generally, not just on Windows, but it doesn't really matter much since it can't be broken on *any* platform.
2017-10-16SDL: Fix 32bpp cursor scaling in SDL1Colin Snover
The SDL1 loop is not very optimal. Unfortunately all our existing scalers only work in 16bpp and I don't have time to fix that right now, so this is fine.

2017-10-15BACKENDS: Constify PaletteManager::grabPalette implementationsColin Snover
2017-10-15BACKENDS: Fix up graphics manager ports with const & override where appropriateColin Snover
2017-10-15SDL: Allow window size to be reset whenever launcher is visibleColin Snover
This ensures the window gets resized properly when a user changes the scaler options in the GUI. Simply unlocking the window size on a call to setGraphicsMode is not good enough, because the scaler mode can be changed by games during mode switches, and we don't want to reset the window size in that case.
2017-10-15SDL: Support 32bpp cursor renderingColin Snover
32bpp cursor scaling is not available, but this should be fine as many of the software scalers are not designed to work with >16bpp data in any case. This change also includes some minor cleanup of unnecessary #ifdefs around code that works equally well with or without USE_RGB_COLOR, to simplify the implementation.
2017-10-15BACKENDS: Fix missing mouse events when system cursor cannot be movedColin Snover
Normally with SDL, a mouse motion event will be sent after the system mouse cursor has been moved by a call to SDL_WarpMouseInWindow, but if the system cursor cannot be moved (e.g. because the window does not have mouse focus), games still need to receive these mouse events so they can successfully update the mouse position internally. Otherwise, games continue to think the mouse is still in the original position and will continue to try to perform whatever action is associated with that mouse position. Refs Trac#9689.
2017-10-15BACKENDS: Do not send mouse events to games occurring outside the game draw rectColin Snover
2017-10-15SDL: Minor code cleanup to declare variables at point of first useColin Snover
2017-10-15BACKENDS: Fix GraphicsManager handling of empty cursorsColin Snover
The SDL graphics manager was just ignoring calls from CursorMan to set the cursor to a blank cursor, which meant engines that did not immediately send a cursor to CursorMan at startup would still show the launcher's cursor (usually with a broken palette). The OpenGL graphics manager would try to generate and draw an invalid cursor surface when receiving an empty cursor.
2017-10-15BACKENDS: Also hide mouse cursor outside game area when an engine has hidden ↵Colin Snover
the cursor The only reason we show the system cursor outside the game area is to show users where their mouse is when the window is resized and the mouse is outside the game area. If the game cannot be interacted with, then the mouse also does not need to be shown in the black areas.
2017-10-15BACKENDS: Refactor OpenGL & SDL graphics backendsColin Snover
This patch refactors the OpenGL and SDL graphics backends, primarily to unify window scaling and mouse handling, and to fix coordinate mapping between the ScummVM window and the virtual game screen when they have different aspect ratios. Unified code for these two backends has been moved to a new header-only WindowedGraphicsManager class, so named because it contains code for managing graphics managers that interact with a windowing system and render virtual screens within a larger physical content window. The biggest behavioral change here is with the coordinate system mapping: Previously, mouse offsets were converted by mapping the whole space within the window as input to the virtual game screen without maintaining aspect ratio. This was done to prevent 'stickiness' when the mouse cursor was within the window but outside of the virtual game screen, but it caused noticeable distortion of mouse movement speed on the axis with blank space. Instead of introducing mouse speed distortion to prevent stickiness, this patch changes coordinate transformation to show the system cursor when the mouse moves outside of the virtual game screen when mouse grab is off, or by holding the mouse inside the virtual game screen (instead of the entire window) when mouse grab is on. This patch also improves some other properties of the GraphicsManager/PaletteManager interfaces: * Nullipotent operations (getWidth, getHeight, etc.) of the PaletteManager/GraphicsManager interfaces are now const * Methods marked `virtual` but not inherited by any subclass have been de-virtualized * Extra unnecessary calculations of hardware height in SurfaceSdlGraphicsManager have been removed * Methods have been renamed where appropriate for clarity (setWindowSize -> handleResize, etc.) * C++11 support improved with `override` specifier added on overridden virtual methods in subclasses (primarily to avoid myself accidentally creating new methods in the subclasses by changing types/names during refactoring) Additional refactoring can and should be done at some point to continue to deduplicate code between the OpenGL and SDL backends. Since the primary goal here was to improve the coordinate mapping, full refactoring of these backends was not completed here.
2017-10-15SDL: Accept signed values for mouse cursor warpingColin Snover
This matches the other ScummVM and SDL APIs for mouse warp.
2017-10-15SDL: Allow window resize with non-OpenGL SDL2 backendColin Snover
The GUI is not redrawn when the window size changes, but that is not as important as being able to resize the games themselves.

2017-10-07BACKENDS: Make initSizeHint an optional extension pointColin Snover
There is no particular reason why backends that don't need to calculate screen dimensions in advance should still need to implement initSizeHint at this point.
2017-10-07BACKENDS: Fix window sizing of games that switch between multiple resolutionsColin Snover
2017-10-07SDL: Deduplicate scaling factorsColin Snover
2017-10-07ENGINES: Remove default1x scaler flagColin Snover
This flag is removed for a few reasons: * Engines universally set this flag to true for widths > 320, which made it redundant everywhere; * This flag functioned primarily as a "force 1x scaler" flag, since its behaviour was almost completely undocumented and users would need to figure out that they'd need an explicit non-default scaler set to get a scaler to operate at widths > 320; * (Most importantly) engines should not be in the business of deciding how the backend may choose to render its virtual screen. The choice of rendering behaviour belongs to the user, and the backend, in that order. A nearby future commit restores the default1x scaler behaviour in the SDL backend code for the moment, but in the future it is my hope that there will be a better configuration UI to allow users to specify how they want scaling to work for high resolutions.
2017-10-07SDL: Do not reset window size when engines update rendering surfaceColin Snover
This change allows: * Engines to update their target rendering surface/size and pixel format with the backend multiple times during gameplay; * Users to resize the ScummVM window without having it reset size/position every time an engine updates its target surface format; * Conversions/scaling to continue to run efficiently in hardware, instead of requiring engines to pick their maximum possible output format once and upscale inefficiently in software; * The window to reset size once when an engine calls to set its initial output size, and to reset again once ScummVM returns to the launcher. This is relevant for at least SCI32 and DreamWeb engines, which perform graphics mode switches during games.
2017-10-06MACOSX: Change name for CoreAudio MIDI deviceThierry Crozat
Also remove a couple of TODOs. I think we can limit the CoreAudio plugin to the Apple DLS softsynth since with have the CoreMidi plugin to access other MIDI devices.

2017-09-15SDL: Remove USE_RGB_COLOR #ifdefs from detectSupportedFormatsColin Snover
This function is only defined when USE_RGB_COLOR is defined so these additional conditions are redundant.
2017-09-12SDL: Remove code for unused DoubleBufferSDLMixerManagerThierry Crozat
2017-09-12OPENPANDORA: Remove unused includeThierry Crozat
The use of DoubleBufferSDLMixerManager in the OpenPandora backend was removed in commit b157269 but the include for it was left behind.
2017-09-12GPH: Remove unused includeThierry Crozat
The use of DoubleBufferSDLMixerManager in the GPH backend was removed in commit 3b6398c but the include for it was left behind.
2017-09-12MACOSX: Remove mixer init from derived class for macosx backendThierry Crozat
Since the macosx backend now does the same as the base SDL backend we can just let the base class do its stuff.
2017-09-12SDL: Stop using double buffering mixer on macOSColin Snover
This mixer type was added in 943b4c2036002454b276e0190dfc2c8919fb0cbf because "anything which produces sampled data with high latency (like the MT-32 emulator) will sound terribly", but as far as I can see (or reproduce), this mixer doesn't do anything that would solve that problem, except that it effectively doubles the size of the audio buffer so there's less chance of an underflow due to slower-than-realtime synthesis by the softsynth. But you don't need the overhead of a separate thread to do that, you just need to increase the buffer size.
