b7ede6cc	2015-06-19T23:20:43	Fixed bug 1550 - SDL_RenderCopy/CopyEx in software should optionally render 8bit alpha Adam M. There are three problems in the code that I see. 1. SW_RenderCopyEx enables a color key on surface_scaled even if the source surface didn't have a color key. 2. SW_RenderCopyEx doesn't copy blend mode, color mod, or alpha mod from src to surface_scaled. 3. When SDL_BlitScaled(src, srcrect, surface_scaled, &tmp_rect) is called, it blends the src pixels into surface_scaled instead of overwriting them (if src has blending, etc. enabled). I've attached a patch that 1) fixes the three problems that I mentioned, 2) adds the requested performance improvement of using the regular blit function if no rotation or flipping is needed, 3) avoids cloning the source surface if no stretching is required, and simplifies the rotation code slightly.
6a3ad8a9	2015-05-28T12:18:05	Fixed bug 2367 - Bad mouse motion coordinates with two windows where one has changed logical size Andreas Ragnerstam I have two windows where one has a renderer where the logical size has been changed with SDL_RenderSetLogicalSize. When I get SDL_MOUSEMOTION events belonging to the non-scaled window these will have been scaled with the factor of the scaled window, which is not expected. Adding some printf debugging to SDL_RendererEventWatch of SDL_render.c, where (event->type == SDL_MOUSEMOTION), I found that for every mouse motion SDL_RendererEventWatch is called twice and the event->motion.x and event.motion.y are set twice for the event, once for each renderer where only the last one set will be saved to the event struct. This will work fine if both renderers have the same scale, but otherwise the motion coordinates will be scaled for the renderer belonging to another window than the mouse was moved in. I guess one solution would be to check that window == renderer->window for SDL_MOUSEMOTION events, similar to what is done for when SDL_WINDOWEVENT events. I get the same error on both X11 and Windows. The same problem also exists for SDL_MOUSEBUTTONDOWN and SDL_MOUSEBUTTONUP events.

b72938c8	2015-04-20T12:22:44	Windows: Always set the system timer resolution to 1ms by default. An existing hint lets apps that don't need the timer resolution changed avoid this, to save battery, etc, but this fixes several problems in timing, audio callbacks not firing fast enough, etc. Fixes Bugzilla #2944.
