Elias Naur ac3ac3ddff shader: introduce a crude setting for adjusting the maximum workgroup size 
Both the Vulkan and OpenGL ES spec allow implementations to limit workgroups to
128 threads. Add a LG_WG_FACTOR setting for easy switching between 128 and 256
threads, with 256 being kept as the default setting.

Manually tested that LG_WG_FACTOR = 0 (128 threads) works as expected.

Raph Levien 6db4e20bbb More parallel backdrop propagation 
This is a nice improvement but still not great on tiger.

Raph Levien af0a1af8e1 Make fills work 
The backdrop propagation is slow but it does work.
