- * I believe the fundamental restriction is that the rasterizer (in

- * rasterized. We need to ensure any coordinates beyond the rasterizer
- * limit are handled by the clipper. So effectively that limit becomes
- * the clipper's guardband size.

- * It goes on to say:
- *
- * "In addition, in order to be correctly rendered, objects must have a
- * screenspace bounding box not exceeding 8K in the X or Y direction.
- * This additional restriction must also be comprehended by software,
- * i.e., enforced by use of clipping."
- *
- * This makes no sense. Gen7+ hardware supports 16K render targets,
- * and you definitely need to be able to draw polygons that fill the
- * surface. Our assumption is that the rasterizer was limited to 8K
- * on Sandybridge, which only supports 8K surfaces, and it was actually
- * increased to 16K on Ivybridge and later.
- *
- * So, limit the guardband to 16K on Gen7+ and 8K on Sandybridge.
