Description Adam M. 2014-05-14 01:33:20 UTC 
Sam Lantinga wrote in bug #2401 that "The texture formats listed in SDL_RendererInfo are sorted in order of preference."

But for the software renderer on Windows, anyway, the texture formats are listed in this order: RGB555, RGB565, RGB888, BGR888, ARGB8888, etc. Is RGB555 really the preferred texture format? That seems unlikely.
Comment 1 Sam Lantinga 2014-06-22 04:47:48 UTC 
Good point. I think that the 565 formats were faster at one point because they move less data, but I'm changing it so the renderers are consistent.

Thanks!
Comment 2 Adam M. 2014-06-22 13:48:13 UTC 
That's understandable, but even if so you'd expect 565 to come before 555, since it's the same number of bytes per pixel but higher quality.

Good point. Fixed!
