Experimental boolean tool optimization: for very large meshes a significant
amount of time is spend performing linear searches of edges. This patch
implements a "hash" table (really more of a bucket table) to narrow the
search space.
If someone should need to disable this, just remove the "#define HASH" at
the beginning of BOP_Mesh.h
Adding back some code to booleans that got lost in the Orange merge.
I've also added back the code which checked that meshes were solid
("manifolds") but have the actual check in
intern/boolop/intern/BOP_Interface.cpp, since from my testing it was
not causing crashes or hangs. It *can* give odd results depending on
what you're trying to intersect, but seems useful. Additionally, since
existing bugs in the current code can create non-solid/non-manifold
meshes, seems hypocritical to create a mesh that can't later be used in
another boolean operation.
BOP_Mesh.h:45: warning: ‘class BOP_Mesh’ only defines private constructors and h
as no friends
drawimasel.c initalized a variable so it didn't give warnings about it.
(wasn't really needed but if the code changes could be potential issue)
