Re: Using OpenGL as a window manager

The main purpose in doing this is to provide clear fonts. In the current X model
the font bitmaps are generated clientside. If xserver is a transform (scaling 2x
or half size or a distortion) then the font generator needs to know this in
order to generate a differenct bitmap.

In a world of infinite resolution and complete scalability there is no bitmap
for the app window.
