Detailed Description

All supported options applying to subdivision scheme.

The Options class contains all supported options that can be applied to a subdivision scheme to affect the shape of the limit surface. These differ from approximations that may be applied at a higher level, i.e. options to limit the level of feature adaptive subdivision, options to ignore fractional creasing, or creasing entirely, etc. These options define the shape of a particular limit surface, including the "shape" of primitive variable data associated with it.

The intent is that these sets of options be defined at a high level and propagated into the lowest-level computation in support of each subdivision scheme. Ideally it remains a set of bit-fields (essentially an int) and so remains light weight and easily passed around by value.
