2020-11-16	Fix T82736, Exact Boolean fail with repeated subtraction of same object.	Howard Trickey
	Two problems were fixed. One, the code for dissolving vertices left a face around if dissolving a vertex would leave less than three vertices. Instead, the face should be deleted. Two, with transformations like "rotate 180 degrees", this should be no problem with exact, but the current transformation matrix has very small non-zero entries where it shouldn't. Cleaning the transformation matrix makes it more likely that user expectations about coplanar faces will be fulfilled.
2020-08-28	Merge newboolean branch into master.	Howard Trickey
	This is for design task T67744, Boolean Redesign. It adds a choice of solver to the Boolean modifier and the Intersect (Boolean) and Intersect (Knife) tools. The 'Fast' choice is the current Bmesh boolean. The new 'Exact' choice is a more advanced algorithm that supports overlapping geometry and uses more robust calculations, but is slower than the Fast choice. The default with this commit is set to 'Exact'. We can decide before the 2.91 release whether or not this is the right choice, but this choice now will get us more testing and feedback on the new code.
