Resetting and recycling of immediate drawing buffers was never done and would leak memory as the buffers were only destroyed when Blender exited. This is solved by not recycling or resetting the buffers and rely on the discard pools. Additional cleanup of removing unused code-paths is also part of this change so it can be backported to 4.5.
