Detailed Description

A RenderPass subclass responsible for rendering selectable objects to a texture.

This pass performs the rendering of selectable objects to a texture that can be
sampled to retrieve the actual object that was underneath the mouse cursor. Additionally,
information about what objects are actually selected is rendered into the alpha channel
of this render pass so it can be used later on in the composite pass.
