  - D3D devices use DISCARD for windowed renderbuffers now, can be faster.
 
- - position2d is now a synonym for vector2d.  position2d is therefore marked as deprecated, although it's unlikely to be removed.
+ - Changed behaviour of PixelBlend16() / PixelBlend16_simd() so that they treat the 1 bit alpha of the source pixel as boolean, i.e. they draw either the source pixel, or the destination pixel, rather than "blending". (Issue revealed by the fix to IVideoDriver::makeColorKeyTexture()).

+ - IVideoDriver::makeColorKeyTexture() bug fixed so that only alphas, not whole texel colors, are zeroed. An optional parameter allows using the old (buggy) behaviour for backwards compatibility.
