RE: [Algorithms] lights/shadows rendering architecture

[Tom F. <tom...@ee...>]

Instead of this:

-Render to texture A
*bubble*
-Render to FB with texture A
-Render to texture B
*bubble*
-Render to FB with texture B

change to this:

-Render to texture A
-Render to texture B
-Render to FB with texture A
-Render to FB with texture B

That way while waiting for the rendering of A to finish, the GPU can =
instead
be doing something useful with its time.
