Previously the snap points computed for oval pads didn't get all the
points correct. This breaks out the "find snap points for ovals"
into a function, reworks the logic, adds some tests.
Also adds "extremum points" when the oval isn't exactly H/V.

Using the new ITEM_MODIFICATION_ROUTINE system, drop in two new
tools: chamfer and line extend. These are two geometric operations
that are relatively common when editing footprints in particular.
Chamfer delegates the geometric calculations to a dedicated unit
in kimath/geometry.
1) Also reorders parameters to make sure the compiler helps out.
2) This also makes it harder to mess up the discrepency between
BOX2I/wxRECT/etc::Inflate() and SHAPE_POLY_SET::Inflate.
3) Also fixes a couple of bugs where the corner strategy was passed
in as a segCount.
4) Also fixes a couple of bugs where the error wasn't forced to the
outside to match the ERROR_LOCATION.
5) Also fixes a couple of bugs where the seg count was specified
without regard to an already passed-in max deviation
1) Don't fracture font glyphs when generating them; we're going
to fracture during triangulation anyway.
2) Don't check for self-intersection when deciding to fracture.
It costs nearly as much as the fracture does.
3) Cache drawing sheet text.
4) Use the current font when checking for cache validity.
5) Parallelize glyph triangulation.
6) Don't invalidate bounding box caches when offset by {0,0}
7) Use the glyph cache when generating text effective shape.
8) Short-circuit NormalizeJustification() if its center/center.
9) Don't triangulate for GuessSelectionCandidates()
10) Avoid sqrt whenever possible.
11) Pre-allocate bezier and SHAPE_LINE_CHAIN buffers.

Adds QA checks to copper sliver tests. Adds the following checks:
- Dot product between two arms (quickly avoids checks for >90°)
- Checks the sliver is convex (area test)
- Eliminates minor slivers with angles that are approximately 0 and ones
with the opposite side width beneath a configurable level
- Updates Clipper2 to fix a couple of jagged edges on inflate
- Adds simplify during zone fill inflation to limit jaggies

acos(1) returns 0, so this implies infinite segements to get to 0 error.
This is not reasonable but might be encountered in bad arcs or circles
that have 0 radius. Instead of returning infinite or std::max segments,
we limit the error to be at least 1 IU
