OptionalminDrop fills with fewer than this many pixels in the owner
buffer. Filters out salt-and-pepper noise from triangles
that only barely win the depth test. Default 4 — low
enough to keep thin features (chair legs, door handles)
once the depth buffer is at the default 2048 resolution.
OptionalsimplifyDouglas-Peucker tolerance, in pixel units. 0.25 (default)
preserves sub-pixel detail at 2048 px while still dropping
the redundant collinear vertices marching squares emits
along straight edges. Set to 0 to keep every
marching-squares vertex.
