Minor syntax fix.

Shifted the dispatch from the algorithm side to the storage side of the
sampling system to keep the code simple.

Now there is a MSurfaceSampleStorage struct that encodes the storage
details, which the algorithms don't have to care about.

Added generalized method for creating an array of mesh samples with
arbitrary stride.

Changed mesh sample definition to use 3 vertex weights instead of a
face index. This is easier to sample uniformly and avoids the need for
tesselation for evaluating.

Normalize the normal vector after sample eval to account for
interpolation.

Added a bool return to the eval function to give feedback on invalid
samples.

Added a basic RNA definition for the mesh sampling system.

Eval function to get a location and normal vector from mesh samples.

Usable random distribution algorithm.

Does not include area weighting yet.
