2018-08-26OPENGL: Use premultiplied alpha for color-keyed cursorsBastien Bouclet
This fixes colour fringing on keyed cursors when using filtering. Fixes Trac#10594.

2018-07-08SDL: Clip mouse range in convertVirtualToWindowMatthew Stewart
2018-07-08SDL: Clip mouse range in convertWindowToVirtualMatthew Stewart
When the graphics scale was 2x or higher, it was possible for the mouse to pass the size of the screen specified by "initSize".

2018-07-08GUI: Add Stretch Mode selection in Options dialogThierry Crozat
2018-07-08SDL: Implement stretch mode APIThierry Crozat
Four modes are supported: - Use original size with no scaling - Scale by an integral amount as much as possible but not bigger than the window. - Scale to fit the window while respecting the aspect ratio. There may be black bars on the left and right, or on the top and bottom, but not both. This is the default, and the old behaviour. - Scale and stretch to fit the window. In this mode the aspecy ratio is not respected and there is no black bars. The mode is controled by the "scaling_mode" value (between 0 and 3) in the config file. Also add Crtl-Alt-s hotkey to cycle through scaling modes

When a non-integral scaling was being used, x and/or y cursor position would be one less than what it should be. Fixes Trac#10401 Thanks snover!

2017-12-03ALL: Remove obsolete register keywordColin Snover
The register keyword was deprecated from the C++11 standard, <http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2014/n4193.html#809>, and removed from the C++17 standard, <http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2015/n4340>, so cannot exist in a well-formed C++17 program. It has never done anything in GCC <https://gcc.gnu.org/ml/gcc/2010-05/msg00113.html> and because of the way it is specified in the standard, it is “as meaningful as whitespace” <http://www.drdobbs.com/keywords-that-arent-or-comments-by-anoth/184403859>. The one remaining use of the register keyword is in the DS backend, where it is used to create a local register variable using the non-standard GCC Extended Asm feature. Closes gh-1079.
2017-12-03SDL: Fix memory corruption when switching to/from 32-bit cursorsColin Snover
When a 32-bit cursor has the same size as an 8- or 16-bit cursor, the mouse surfaces were not being regenerated even though the 32-bit cursors have a different memory requirement. This lead to memory corruption as an inappropriate surface would be used for the other type of cursor. The shoe-horned 32-bit cursor support is clearly showing its scrappy nature here and probably ought to be revisited in the future if the SurfaceSdl graphics manager sticks around. Fixes Trac#10349, Trac#10350, Trac#10351.

2017-12-01BACKENDS: Fix shake position getting stuckColin Snover
If a game is doing a screen shake (for example, DOTT when the stereo is on), and the user does an RTL, the screen shake offset may get stuck if the engine does not reset it on shutdown. To avoid this in all cases, just always reset the screen shake whenever the graphics manager is told to switch to a new graphics mode.
2017-11-29SDL: Don't use the window size hint for fullscreenBastien Bouclet
Prevents the opengl backend from changing mode when entering fullscreen for games with a window size hint. Fixes #10335. Closes gh-1074.
2017-11-27SDL: Store fake mouse warp event in virtual coordinatesColin Snover
Normally, notifyMousePosition converts real mouse events into the virtual coordinate system, but events only get sent through notifyMousePosition if they are real events from SDL since that method also decides if the real mouse is inside the content area or not. As such, these fake events need to be pre-converted to virtual coordinates or else the wrong values are sent through to the engine when a scaler or AR correction is in use.
2017-11-15SDL: Don't pass null pointers to SDL_DestroyTexture/SDL_DestroyRendererColin Snover
SDL does not like this and will raise an assertion when built with internal SDL assertions turned on. With internal assertions turned off, it will still call SDL_SetError any time a null pointer is passed, though it will not raise an assertion or crash.
2017-11-11SDL: Fix assertion when using 4bpp cursors with a key colorBastien Bouclet
Myst ME uses such cursors.
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.
2017-10-19SDL: 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: 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.
