1. An apparatus comprising: a graphics processor to process graphics data and render images using the graphics data; and a non-uniform rasterizer within the graphics processor to determine different resolutions to be used for different regions of an image, the non-uniform rasterizer to receive a plurality of polygons to be rasterized and to responsively rasterize the polygons in accordance with the different resolutions; wherein to rasterize the different regions of the image using different resolutions, the non-uniform rasterizer is to subdivide each image into a plurality of tiles, wherein different tiles are formed using different numbers of image pixels to implement the different resolutions; wherein each tile includes a specified number of scaled pixels and wherein a resolution of a tile is defined by a number of image pixels used to form each of the scaled pixels; and wherein the non-uniform rasterizer is to determine the different resolutions for different regions by reading layout bits used to configure the non-uniform rasterizer, the layout bits specifying how tiles with different resolutions are positioned within each image.
