Chad Brokaw a8585781cd move atlas rect to info 
Atlas offset and image size were originally stored in the ptcl but are not tile dependent. Moving these to info saves 8 bytes per image tile.

Chad Brokaw 033870d91e Fix brush transforms 
This fixes an incorrect application of the inverse transform for radial gradients in fine.

Also fixes an edge case in `SceneBuilder` where a brush transform is identical to the path transform leading to a corrupt encoding.

Chad Brokaw 1e8d194b6a initial GPU side work for robust memory 
This should handle everything on the GPU side except for blend stack loading/storing in fine.

Update references to piet-gpu where it makes sense (#240) 2023-01-08 16:15:51 +00:00
Raph Levien 29a16eb210 Fixes to fine rasterization 
The area bug was found and fixed by @dfrg, and is adapted from #239. I wanted to move it to a separate PR so that one would be more focused on API.

The other bug is currently silent because the two quantities swapped are both 4, but it is triggered when experimenting with tuning for performance.
