This example implements projective cascaded shadow mapping. This technique splits up the camera frustum into

multiple frustums with each getting its own full-res shadow map, implemented as a layered depth-only image.

The shader then selects the proper shadow map layer depending on what split of the frustum the depth value
to compare fits into.
This results in a better shadow map resolution distribution that can be tweaked even further by increasing
the number of frustum splits.
A further optimization could be done using a geometry shader to do a single-pass render for the depth map
cascades instead of multiple passes (geometry shaders are not supported on all target devices).
