Bitmaps loaded via wx can contain alpha channels. We utilize underlying
routines to correctly map the alpha. This also standardizes the Cairo
alpha calls to ensure correct display in Fallback for partially
transparent highlights

Cairo supports antialiasing when rendering but can be slow when set to
sub-pixel mode. This bumps the minimum version of Cairo to 1.12
(available in 14.04 LTS as well as mingw) to support three antialias
settings (fast, good, best) that offer speed/appearance tradeoffs.
This can provide a higher-quality eeschema render as it works on a
per-element basis as opposed to the OpenGL per-screen antialias.
If a page layout contains bitmaps and is used in all sheets of a hierarchy, and in the board editor,
the cross-probing from pcbnew to eeschema invalidate textures associated to these shared bitmaps,
when switching active sheets.
Usually a crash happens after switching or when closing editors.
As a workaround, I disabled bitmaps (therefore associated textures) cache.
Not optimal, but at least it avoid crashes.
Due to the implicit floor of the cast from double to unsigned char,
there was a small rounding error in COLOUR4D's WX conversion function.
This fixes the failing tests.
Also make the cast to unsigned char explicit.
Display GALs had an incorrect world unit value set. Now the world unit
value says how many internal units are in an inch, in accord with the comments
in the GAL header. Bitmap drawing code relied on the information about DPI,
so scaling worked differently for display and print GALs.
CAIRO_PRINT_CTX provides a Cairo context created from wxPrintDC.
It allows one to prepare printouts using the Cairo library and
let wxWidgets handle the rest.
Fixes a crash when typing fast in the place footprint filter box.
Also adds a bunch more checking to GAL locking, including making
sure the same person unlocks as locked, and preventing piece-meal
calls (the RAII objects must be used).
It happens when the char is not found in the font used to display netnames/pad names.
When happens, a wxASSERT is raised.
Unfortunately it can crash the application if it is during a paint event or some critical time.
This prevents deadlocks when exceptions are thrown and the context
ends up not getting unlocked.
It also removes an earlier hack to try and minimize this which
didn't work anyway.
Split antialiasing options out from display options. Move
antialiasing to common. Duplicate the rest of display options
for Eeschema.
Implement OnSelectGrid and hookup GAL canvas refresh to
SetPresetGrid.
Add Grid Settings... to View menu and move Show Grid from
preferences to View Menu to match Pcbnew.
Happens only in Opengl mode.
So enforce controls in 3 group function: DrawGroup, ChangeGroupColor, ChangeGroupDepth.

Replaces Poly2Tri with updated code to process polygons faster and more
robustly. Notably, we can now handle overlapping holes in the polygons,
allowing us to cache the triangulation of complex boards
Be more intelligent about sorting lib tree items. (Footprint
entries, for instance, come out of an already-sorted list.)
Don't recreate menus twice when laoding Footprint Editor.
More pervasive use of WX_FILENAME to avoid expensive calls to
wxFileName::SplitPath() and string concatenation.
For POSIX kernels do all the work on the file-system side so we
don't have to keep converting back and forth between encodings.
