Thanks to Chris Warren-Smith for testing this a bit.

The hooking code is nearly exactly the old hooking code. Only the OpenGL SDL
creation has been adapted since it uses a different constructor now.
|
|
This backend is based on ideas of the old OpenGL backend, of the Android GL
backend and of the iPhone GL backend.

This is a first step to get rid of OverlayColor, which is a requirement for
proper 4Bpp overlay support.

This is mainly for consistency with OSystem::copyRectToScreen.

*" as buffer.
This removes the need to convert the parameter to copyRectToScreen to
"const byte *", which is commonly used in games, which use Graphics::Surface
to store their graphics data.

logic.
All uses of the old target scale API actually wanted to disallow scaling of
the mouse cursor. This commit adapts our API to this and thus simplifies
backend implementations.
Some backends, most notable the Wii and Android, did some implementation of
the cursor target scale, which I didn't adapt yet. I added a TODO for the
porters there.

Now only 320x200 and 640x400 will result in aspect ratio correction to be used
if the user requested it. This should fix some strechting in Myst/Riven.

This gets rid of the hacks, where SdlEventSource added events with custom type
numbers to pass SDL_VIDEOEXPOSE and SDL_VIDEORESIZE to the graphics manager.
Furthermore it get rids of the uninituitive and hard to trace way of assigning
the proper mouse coordinates to mouse related events. Formerly it passed the
real screen coordinates through the even dispatching api to the graphics
manager (at least hopefully ;-) and let that handle creating a new event with
the proper coordinates. Now instead SdlEventSource handles the proper
coordinate setup itself.
Since this is a behavior change and I can not test all the SDL based small
devices ports this commit might break compilation for them and more serve it
might also break mouse position behavior. If any of that occurs I am sorry
about it.

This tries to make our code a bit more compliant with our code formatting
conventions. For future use, this is the command I used:
git ls-files "*.cpp" "*.h" | xargs sed -i -e 's/[ \t]*$//'

mode for it.
This partly fixes the OpenGL mode mess, but now OpenGL Normal and OpenGL
Conserve will feature the same semantics when aspect ratio correction is
enabled... That is still something to solve.

First step into making all state variables of the OpenGL backend private, to
help making the backend more maintainable, by disallowing subclasses to just
mess with everything...
|
|
This fixes annoying graphics glitches, which occured sometimes when resizing
the Window.
|
|
Now subclasses will not need to worry about the scaling logic themselves, but
just need to implement setInternalMousePosition, which should handles setting
the system's mouse coordinates.
|
|
Rather than that I introduced a function which converts hardware screen
coordinates to overlay / game screen coordinates.
The logic which converts mouse movement events with hardware screen
coordinates to overlay / game screen coordinates is now inside notifyEvent.
This is still broken design, since one should not abuse an observer for that.

This actually still has the drawback that if one calls OSystem::updateScreen
from the sound thread that it might crash. Hopefully no code does this though...

Now the previous aspect ratio modes are handled as GFX modes. The previous
GFX modes were for scaling, but are removed now. A new 4/3 display mode
added. Added Ctrl-Shift-A for backward switching through display modes, and
Ctrl-Alt-<number key> for switching to a specific GFX mode.
Window resizing now is available for all display modes, and will
automatically change the scale factor as well as maintain the aspect ratio
when needed.

OpenGL context may be destroyed after calling SDL_SetVideoMode, so it is better to always recreate the textures.

fullscreen toggling default mode selection.
Floats can lead to calculation errors because, now uints are used and aspect ratio values are handled with a x 10000 scale.
When entering fullscreen, it will be looked for the fullscreen mode with the smallest metric that mantains the game screen aspect ratio.

OSystem_SDL will create a merged list of all graphics modes from SDL and OpenGL. When the user changes the graphics mode in options and restarts ScummVM should switch to that graphics mode in the corresponding graphics manager.

This fixes a hack for resetting the graphics scale to x1 when starting games that have a large screen size. The SDL graphics manager should now scale back to x1 without changing the current scaler in use, as well as the OpenGL graphics manager.
