The computation to adjust patch evaluation weights
for box spline triangle patches to account for boundaries
has been updated to use simple conditional logic instead
of index indirection tables. This results in better register
resource usage for some shader compiler implementations.
Previously, these methods could fail to compile on some
systems.
