939 * "The vertex X and Y screen-space coordinates are also /clamped/ to the
940 * fixed-point "guardband" range supported by the rasterization hardware"
944 * "In almost all circumstances, if an object’s vertices are actually
945 * modified by this clamping (i.e., had X or Y coordinates outside of
946 * the guardband extent the rendered object will not match the intended
947 * result. Therefore software should take steps to ensure that this does
948 * not happen - e.g., by clipping objects such that they do not exceed
949 * these limits after the Drawing Rectangle is applied."
951 * I believe the fundamental restriction is that the rasterizer (in
952 * the SF/WM stages) have a limit on the number of pixels that can be
953 * rasterized. We need to ensure any coordinates beyond the rasterizer
954 * limit are handled by the clipper. So effectively that limit becomes
955 * the clipper's guardband size.
959 * "In addition, in order to be correctly rendered, objects must have a
960 * screenspace bounding box not exceeding 8K in the X or Y direction.
961 * This additional restriction must also be comprehended by software,
962 * i.e., enforced by use of clipping."
964 * This makes no sense. Gen7+ hardware supports 16K render targets,
965 * and you definitely need to be able to draw polygons that fill the
966 * surface. Our assumption is that the rasterizer was limited to 8K
