[libcvd-members] GLWindow size%4 constraint..

[Georg Klein]

What's the reason for the line

state->size = ImageRef(event.xconfigure.width & (~0x3), event.xconfigure.height 
& (~0x3));

in gl_window.cc? It makes the internal size parameter incorrect, resulting 
in black margins on non-multiples of four. Any reason to keep this?
