2005-11-25 Thread Brian Paul
I've been playing around with the EGL r200 driver. Digging through the framebuffer allocation code I've found a few problems. In order to support pbuffers and framebuffer objects we need to be able to work with color/depth/stencil buffers are various locations in video memory. The current
