M lib/ivis_opengl/piedraw.cpp
Log Message:
-----------
Aggregate shadow vertices and batch glDrawArrays calls
Instead of a `glDrawArrays` call for every shadow-casting shape, aggregate
vertices that are pre-multiplied by the `modelViewMatrix`, and batch
`glDrawArrays` calls. This massively reduces the number of gl calls (both for
filling buffers and drawing) as now only a single (large) buffer needs to be
allocated and streamed per call to `pie_ShadowDrawLoop`.
