774c5c2400 fix convex hull failure case when tolerances are used to discard points, and the best point has a reported plane distance less than zero due to floating point error (but the exact test has reported that the point is on the correct side of the plane)

f70478d4f0 Moved some bool-taking container wrappers over to using EAllowShrinking. 
FGraphAStar::PopIndex() isn't passing on its argument to the container - that existing behavior has been retained.

1fb821235a make negative space sampling default to 'deterministic' mode, and make that mode sort the vertices after marching cubes has run rather than disabling parallelism during marching cubes. 
also always run the point prioritization step, and don't early-stop it if we may take more samples than the minimum requested.

d205e117bb GeometryProcessing: various utility functions to assist with rounded bevels implementation 
- add 2D version of VectorTanHalfAngle to VectorUtil.h
- add FDynamicMeshUVEditor::SetToPerVertexUVs, initializes overlay to have a single UV for each vertex
- add FQuadGridPatch::InitializeFromQuadPatch(), initializes the quad grid from external rows of quads and associated vertices
- add FQuadGridPatch::GetVertexColumn(), returns the list of vertices in a specific grid column
- add FQuadGridPatch::FindColumnIndex(), finds the index of the grid column that contains a specific Vertex ID

bca502e8cd Fix convex decomposition's min sample spacing test to run after finding the final sample location, rather than running on the initial estimate location, so it will function as intended when the samples are placed far from their initial estimate locations.

bf3ae9cbd2 better simple collision level set visualization: add optional marching-cubes-based level set triangulation to the simple-collision->mesh utility functions and use the new marching cubes triangulation in tools + optionally in geometry script's append simple collision function. 
also do some cleanup / generalization of the utility functions and change geometry script's append simple collision function to use them.
