Jeff Young cba430deab Fix undo/redo and revert for libedit name changes and aliases
Three interrelated issues:
1) Implement an undo/redo type for renames so that we know to delete
the old lib entry and add a new lib entry
2) When doing so (for the undo/redo OR the original edit), we must
make a copy of the 'original' LIB_PART which is used for revert, and
hand it to the new lib entry
3) When comparing a modified component tree item with the current item
we must also check for aliases.

Chris Pavlina 7e6a6540c8 Implement primitive icon scaling for high DPI
This is meant as a stopgap for 5.0, with plans to add proper scaled
icons in the 6.0 cycle. A function KiScaledBitmap() is added, which
works like KiBitmap() except it scales the bitmap according to the
calling window's font size. Controls have been added to all the main
applications to let the user select scaling manually (these were omitted
from smaller apps that didn't already have a place to put them).

In addition, in eeschema only, the pixel height of the system font is
shown in the options dialog for diagnostics. This is only for collecting
feedback before 5.0 release from users with different displays and will
be removed.

are simple string comparisons.

Andreas Buhr b33bf2eafe fix double free and memory leak in SHAPE_POLY_SET
There were two problems in the triangulation caching
of SHAPE_POLY_SET:
First there was a double free:
While SHAPE_POLY_SET implements the copy constructor,
it did not implement the operator=, which resulted
in the default operator= being generated by the
compiler. The default operator= copied the member
m_triangulatedPolys, which is a std::vector of pointers.
So after operator= execution, there are two SHAPE_POLY_SET
having pointers to the same TRIANGULATED_POLYGONs, each
of them deleting them in their destructors. This led
to segfaults, because calling
TransformShapeWithClearanceToPolygon on a Zone
uses operator= to copy the contained SHAPE_POLY_SET.
The new SHAPE_POLY_SET then went out of scope and
deleted the cached triangulation within the Zone.

This first problem is fixed by implementing operator=
for SHAPE_POLY_SET.

Second, there was a memory leak: Calling
"CacheTriangulation" on a SHAPE_POLY_SET,
then changing the polygon and then calling
"CacheTriangulation" again led to
leaking the
triangulations generated in the first call.

This second problem is fixed by holding
the cached triangulations in a unique_ptr.
