- Fix blend constant handling when the
PAN_BLEND_SHADER_MAX_VARIANTSlimit is hit
- Fix crashes with combined stencil for debug builds
- Avoid preloading stencil when it is known to be a constant value
I'm not sure that just increasing
PAN_BLEND_SHADER_MAX_VARIANTS is the best thing to do. The "Colors" page of
systemsettings5 uses 32 different variants on my system, but when more themes are installed this will be greater.
At this size, the overhead of searching the linked list may start to become significant if lookups are required often. Maybe other data structures should be considered, but I'm not convinced that the problem is big enough to warrant that.
