RenderGlowMgr
A render bin for the glow pass.
Detailed Description
A render bin for the glow pass.
When the glow buffer PostEffect is enabled this bin gathers mesh render instances with glow materials and renders them to the #glowbuffer offscreen render target.
This render target is then used by the 'GlowPostFx' PostEffect to blur and render the glowing portions of the screen.
