Syntax
class FInsetMeshRegion
Remarks
FInsetMeshRegion implements local inset of a mesh region. The selected triangles are separated and then stitched back together, creating an new strip of triangles around their border (s). The boundary loop vertices are inset by creating an offset line for each boundary loop edge, and then finding closest-points between the sequential edge pairs.
Complex input regions are handled, eg it can be multiple disconnected components, donut-shaped, etc
Each quad of the border loop is assigned it's own normal and UVs (ie each is a separate UV-island)
