Standard GUI framework inspired by Qt

[karl via Digitalmars-d]

SDL2: Chooses the deprecated color-mode in GLX; prevents you from 
creating a core context; keeps the baseline as if everyone has 
only hardware from 2001 or earlier that somehow still works; 
while preventing batching at every single operation. glBegin, 
glRectf, glReadPixels+manually_flip_y+convert(). It's not the 
thing you want for rendering 16k+ glyphs and items onscreen in a 
GUI.

16-48ms : drag/resize something in an existing GL GUI. Or even 
better, disable your mouse hw accel (it's an overlay thing, right 
before the RAMDAC) (but still GL-accelerated by your compositor 
of choice). You'll see what I mean. Also, latency != rate.
