Changes a dot to be a square pixel (linewidth x linewidth). This allows
the removal of IU dependencies and ensures that a dot is always visible
on screen. Also makes sure that cairo is setting the current linewidth
during its stroke routines

Previously, the count of segments used a magic number optimized for Pcbnew.
This is not good, and does not work well on Gerbview.
The count uses now a max error acceptable is approximation (5 microns in Gerbview and Pcbnew).

Reduce each (Accel & Fallback) to 3 options: Off, Fast, Good. Fast AA
in accelerated canvas uses SMAA with tweaks suggested by David Beinder.
Good AA is super-sampled x2.
Cairo is similarly reduced to Off, Fast, Good, which map to the Cairo
options themselves. Best is removed as it mostly affects text rendering
and not line drawing (as our text is)
The native cursor must be set on the GAL canvas wx object,
not its frame (otherwise on GTK the cursor is only set
when we get a request for it from the WM and not immediately).

Cairo Polyline and Polygon draw functions share a common routine. While
Polygons must have 3 points to allow triangulation, a polyline (like our
text) need only have 2
This resolves a crash when passing an empty polygon and alerts debug
users to possible generation cases when bad polygons are created.
Thanks for Frans Zellman
(https://gitlab.com/kicad/code/kicad/-/merge_requests/365) for
identifying the issue.
The base GAL has the linewidth property already, and its
accessor will only return the base version. This was causing
problems with the Cairo printing GAL, since that setter wasn't
using the base class version. Also, this removes the print-specific
setter, since the actual setting of line width shouldn't be done
there and is instead done where the drawing happens.

* Split up the thirdparty code into the thirdparty folder (#3637)
* Create a new kimath static library containing all the math functions
This is part of cleaning the build system for #1906.
Previously, a 600 DPI was used to set device scale (can create minor visible rounding issues).
Using now 4800 DPI to reduce these rounding artifacts.

It was due to a angle normalization between -360 and 360 degrees.
So, in arcs, if the start angle and end angle diff is n*360 deg,
this normalization gives start angle = end angle.
The fix forces end angle = start angle+360deg in this case.

This allows a const BITMAP_BASE to expose const image
data. This is currently done with const_casts, which is
"OK", only as long as the source image is not declared
const, in which case it's undefined behaviour.
Also immediately dereference the pointer to a reference
if it's not checked to make the non-null requirements
explicit at the point of access.
