Change Details

This patch is (almost) a complete rewrite of workbench engine. The features remain unchanged but the code quality is greatly improved. This also introduce the concept of `DRWShaderLibrary` to make a simple include system inside the GLSL files. I did not see any performance change at first glance but this needs more testing. What it fixes - Infront with transparent object is now possible. - No more trick with the stencil buffer for wireframe masking. - Lower memory usage: Buffers are the same for the transparent and opaque passes. All compositing happens on main framebuffer - Replace WORKBENCH_Material allocations/setup/hash with UBOs containing materials properties in chunks of 4096 materials. - Remove a lot of shader variations. - Unify the opaque and transparent pipelines. - Offscreen rendering broken under some circumstances. Remaining Regression: - ~~Bug with TAA when operators setting overlay values not tagging view_updated. (needs to be fixed ASAP)~~ Done - This patch seems to affect roughness a bit. This seems to be caused by the new encoding inside the material. (very low prio) - Hair rendering seems to be a bit brighter. Might be caused by the roughness change. - `In front` objects don't recieve SSAO (cavity effect) anymore. (design decision) - `In front` objects don't behave correctly with Depth Of Field effect. (same design decision as SSAO but could be fixed if enough demand for it) - ~~All shader variations are compiled when opening blender. (optimization task)~~ This does not seems to be a concern in my tests.
