Implemented more flexible blending modes for accelerated renderers
This fixes bug 2594 - Propose new blend mode, SDL_BLENDMODE_BLEND_DSTA
blendMode = SDL_ComposeCustomBlendMode(SDL_BLENDFACTOR_SRC_ALPHA,
SDL_BLENDFACTOR_ONE_MINUS_SRC_ALPHA,
SDL_BLENDOPERATION_ADD,
SDL_BLENDFACTOR_ZERO,
SDL_BLENDFACTOR_ONE,
SDL_BLENDOPERATION_ADD);
This fixes bug 2828 - Subtractive Blending
blendMode = SDL_ComposeCustomBlendMode(SDL_BLENDFACTOR_SRC_ALPHA,
SDL_BLENDFACTOR_ONE,
SDL_BLENDOPERATION_SUBTRACT,
SDL_BLENDFACTOR_ZERO,
SDL_BLENDFACTOR_ONE,
SDL_BLENDOPERATION_SUBTRACT);
This goes partway to fixing bug 3684 - Add support for a pre-multiplied alpha blending mode
blendMode = SDL_ComposeCustomBlendMode(SDL_BLENDFACTOR_ONE,
SDL_BLENDFACTOR_ONE_MINUS_SRC_ALPHA,
SDL_BLENDOPERATION_ADD,
SDL_BLENDFACTOR_ONE,
SDL_BLENDFACTOR_ONE_MINUS_SRC_ALPHA,
SDL_BLENDOPERATION_ADD);

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!

Making the API simpler, the blend modes are "none, blend, add" and are supported by all renderers.
