Depth buffer description

following draw calls will use the buffer as 6 pages width with a scissor
test of 384x672. So the above texture can be seen as a
* texture width: 6 pages * 64 pixels/page = 384
* texture height: 70/6 pages * 64 pixels/page =746
So as you can see the GS issue a write of 640x448 but actually it
