4862c1fc30 Updated blend semantics so blending uses the following formula: 
dstRGB = (srcRGB * srcA) + (dstRGB * (1-srcA))
    dstA = srcA + (dstA * (1-srcA))
This allows proper compositing semantics without requiring premultiplied alpha.

Needs full unit test coverage and bug fixes!

75029512ef Split SDL_BlitScaled into SDL_UpperBlitScaled and SDL_LowerBlitScaled. 
Fixed issue when calling SDL_BlitScaled() directly with src or dst rectangles that were out of bounds.

b59da3ffdc Changed the concept of a render clip rect to a render viewport. 
The render viewport is automatically re-centered when the window changes size, so applications that don't care will not have to handle recalculating their rendering coordinates.

Fixed API for drawing and filling multiple rectangles - the parameter should be an array of rects, not an array of pointers to rects.

Fixed API for updating window rects for consistency with other APIs - the order is pointer to array followed by count in array.

8c8191deef Software scaling support. Not very fast, but it seems to work. 2011-02-14 11:50:18 -06:00

c7b5cc946d A few fixes: 
Fixed creating render texture framebuffer.
Removed the need for palette watch, added surface format caching.
Added an SDL_DONTFREE flag so you can't free the window and 1.2 shadow surfaces.

471a85fb52 Making the API simpler, scaling is always defined as linear interpolation and should be supported as much as possible on all renderers. 2011-01-31 22:44:43 -08:00

c3629ff44a Added SDL_RenderClear() as a fast method of clearing the screen to the drawing color. 
Renamed SDL_RenderPoint() and SDL_RenderLine() to SDL_RenderDrawPoint() and SDL_RenderDrawLine().
Added API for rectangle drawing (as opposed to filling)
Added placeholder API functions for circles and ellipses ... I'm not sure whether these will stay.
Optimized software line drawing quite a bit.
Added support for Wu's anti-aliased line drawing, currently disabled by default.
