UVTile

Modifies the uv mapping at render time supporting the notion of a uv tile - which is a uv region greater than 0-1.

For example, tile [1, 0] corresponds to the u range 1.0-2.0, and the v range 0.0-1.0.  Tile [0, 3] is the u range 0.0-1.0 and the v range 3.0-4.0.

note: The OpenGL preview will not be correct for all modes, especially when there are multiple Materials chained together which modify uvs (a Project3D as an input for example.)  The render should look correct however.

note2: When the renderer is in UV unwrap mode the merging of materials becomes somewhat pointless as all the UV ranges overlap.  What would be nice is if the renderer's UV range could be expanded so that merged tiles would map into their own range in the output image.  However this can't be done right now (that I can tell.)
