A method of rendering graphics data in a graphics processing unit, the method comprising: determining a stencil sampling rate for determining a coverage value for each antialiased pixel of a path of an image, wherein the stencil sampling rate indicates, for each antialiased pixel, a memory allocation in a stencil buffer for storing samples of each antialiased pixel sampled at the stencil sampling rate; determining, separately from the stencil sampling rate, a render target parameter that is less than the stencil sampling rate, wherein the render target parameter indicates, for each antialiased pixel, a memory allocation in a frame buffer for storing each rendered antialiased pixel of the path; rendering the path using the stencil sampling rate and the render target parameter, wherein rendering the path comprises: rendering the path to the stencil buffer using the stencil sampling rate, wherein the stencil buffer indicates which pixels of the path are inside of a fill area for the path; determining, while rendering the path to the stencil buffer, a bounding box for the path, wherein determining the bounding box comprises determining a plurality of maximum boundary points of the path; and rasterizing the path using the render target parameter and the stencil buffer, wherein rasterizing the path comprises shading the pixels inside of the fill area for the path using the bounding box and the stencil buffer, and storing a rasterized version of the fill area for the path in the frame buffer using the render target parameter. determining a stencil sampling rate for determining a coverage value for each antialiased pixel of a path of an image, wherein the stencil sampling rate indicates, for each antialiased pixel, a memory allocation in a stencil buffer for storing samples of each antialiased pixel sampled at the stencil sampling rate; determining, separately from the stencil sampling rate, a render target parameter that is less than the stencil sampling rate, wherein the render target parameter indicates, for each antialiased pixel, a memory allocation in a frame buffer for storing each rendered antialiased pixel of the path; rendering the path using the stencil sampling rate and the render target parameter, wherein rendering the path comprises: rendering the path to the stencil buffer using the stencil sampling rate, wherein the stencil buffer indicates which pixels of the path are inside of a fill area for the path; determining, while rendering the path to the stencil buffer, a bounding box for the path, wherein determining the bounding box comprises determining a plurality of maximum boundary points of the path; and rasterizing the path using the render target parameter and the stencil buffer, wherein rasterizing the path comprises shading the pixels inside of the fill area for the path using the bounding box and the stencil buffer, and storing a rasterized version of the fill area for the path in the frame buffer using the render target parameter. rendering the path to the stencil buffer using the stencil sampling rate, wherein the stencil buffer indicates which pixels of the path are inside of a fill area for the path; determining, while rendering the path to the stencil buffer, a bounding box for the path, wherein determining the bounding box comprises determining a plurality of maximum boundary points of the path; and rasterizing the path using the render target parameter and the stencil buffer, wherein rasterizing the path comprises shading the pixels inside of the fill area for the path using the bounding box and the stencil buffer, and storing a rasterized version of the fill area for the path in the frame buffer using the render target parameter.
