This is the second try at 5326c36a5f. The difference here is that we
have moved GL_CONTEXT_MGR into kicommon first which will hopefully
address some of the Windows linkage issues
The GL context lock needs to be shared across kifaces. Otherwise, we
can end up blocking the lock from one kiface. Unfortunately, I can't
find the issue in GitLab right now for where the footprint viewer shows
a blank screen after opening too many contexts. But that's what this
fixes.

Recommendation is to avoid using the year nomenclature as this
information is already encoded in the git repo. Avoids needing to
repeatly update.

Improves rendering performance, esp. for large designs by:
- using a separate glDrawArrays calls() for large buffers of contiguous vertices (e.g. large zone fills)
- pooling smaller items into a small-sized index buffer held in system RAM (has to be DMAed to the GPU by the driver anyway)
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).

Avoid fractional pixel offsets by forcing integer division of m_screenSize.
Shift rounded lookAtPoint onto OpenGL pixel center to ensure consistent rounding to int.
The pixel 0..1 @ 1x needs to fill the area 0..2 @ 2x so its center moves by 0.5 * (pixel size @ 1x).
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).

Vertex memory allocation uses malloc and realloc without checking the
result. Throw exceptions that can be caught in the DoRepaint() method
in EDA_DRAW_PANEL_GAL when malloc and realloc return a null pointer.
