| 1. A method implemented by a computing device for scan converting data, the method comprising:
directly transforming shape geometry, scanline-by-scanline, into non-graphics device memory as compressed scan converted data,
the shape geometry comprising one or more of shape and position attributes associated with one or more objects; and
wherein the compressed scan converted data is available to an application for subsequent decompression and copying into graphics
device memory for rendering;
wherein directly transforming the shape geometry further comprises encoding blending-based anti-aliasing information to generate
the compressed scan converted data.
