Because the blend mode is explicitly set to SDL_BLENDMODE_NONE, it doesn't matter if there's a transparency channel in the texture format or not for opaque windows. This ensures that a 32-bit format is used with Metal instead of SDL_PIXELFORMAT_RGB565.
Now this keeps one FBO for each SDL_TEXTUREACCESS_TARGET texture, and doesn't
reuse it. We check if the FBO is "complete" once, at creation time, and
setting a render target merely has to bind the right FBO and never look back.
This simplifies the code and removes a guaranteed pipeline stall when setting
a new render target.
Fixes#15524.
CAudio::~CAudio() waited on MaoscBufferCopied(KErrAbort) to set
EStateDone, but that callback can never fire once the active scheduler
loop has exited, deadlocking every close.
- StopThread() before iStream->Stop() in ~CAudio()
- Force iState = EStateDone instead of waiting on a dead callback
- Add 5s timeout to AudioIsReady() poll in E32Main()
- Fix CleanupStack LIFO pop order (mainApp before gRenderer)
Some compositors may dispatch this too early, during the initial empty commit, when subsurfaces are attached to a toplevel window, but a buffer has yet to be committed to the parent surface. Don't set the frame callback until the initial empty commit is done, so it will be called when the actual parent surface frame is committed.
Implement DrawGeometry using a software scanline rasteriser that fills
triangles directly into the EColor4K framebuffer. Vertices are sorted by
Y, split into upper/lower halves and filled with per-scanline edge
interpolation. Colour is stepped incrementally across each span (one
division per span edge rather than per pixel) to avoid the cost of
emulated integer division on the ARM920T.
[N-Gage] Audio is now double buffered to avoid stuttering and glitches. Some audio platform specific variables were exposed through SDL_Hints. Same method was used to display FPS. N-gage functions to obtain the current buffer and screen pitch were added to the render.
Adds hints:
SDL_AUDIO_NGAGE_LATENCY
SDL_AUDIO_NGAGE_SCHEDULER_TICK
SDL_AUDIO_NGAGE_PROCESS_TICK
SDL_AUDIO_NGAGE_PROCESS_PRIORITY
SDL_RENDER_SHOW_FPS
Adds functions to get current buffer address and pitch:
void *NGAGE_GetBackbufferAddress(void);
int NGAGE_GetBackbufferPitch(void);
