Raph Levien	d948126c16	Adjust workgroup sizes ... Make max workgroup size 256 and respect LG_WG_FACTOR. Because the monoid scans only support a height of 2, this will reduce the maximum scene complexity we can render. But it also increases compatibility. Supporting larger scans is a TODO.	2021-12-08 11:48:38 -08:00
Raph Levien	c503ff28b0	Make shaders cross-platform ... Translate all piet-gpu shaders into DXIL and MSL; move generated files into the shader/gen directory.	2021-12-03 15:49:58 -08:00
Raph Levien	47f8812e2f	Start work on new element pipeline ... There's a bit of reorganizing as well. Shader stages are made available from piet-gpu to the test rig, config is now a proper structure (marshaled with bytemuck). This commit just has the transform stage, which is a simple monoid scan of affine transforms. Progress toward #119	2021-11-24 08:01:43 -08:00
