! Virtual Display Blitter Compute Surface

A display-style blitter interface repurposed as a compute surface whose raster
operations become command or state packets.

!! Why It Matters

It gives the GPU/FPGA fabric a software-facing shape: the GPU can write like it
is painting, while the verification side decodes the raster stream as state.
