John Beard 567bdd9b9d Add configuration of Hi-DPI canvas scaling in OpenGL
First, add automatic detection of toolkit DPI scaling options. For now, this
is, in order,

* Check the GDK_SCALE option under GTK+ (users can set this to force the scaling)
* Check the value from WX's GetContentScalingFactor(). This will start to work
  correctly from WX 3.1 and GTK+ 3.10.

Then, add a user-settable override in the main prefs panel, next to the icon
scaling. This is independent of the icon scaling options.

DPI handling is performed in a standalone class, so they can be shared between
the prefs UI and the OpenGL backend easily. Also means Cairo could use the same
interface in future.

Also adjust the OpenGL grid drawing code to use the computed scale factor,
which avoids over-thick grids in scaled environments (the user can manually
thicken the grid if wanted).

Seth Hillbrand f1a60832e0 opengl: Handle stroked semi-circles
And filled but we don't use those yet.  No pixel-alignment needed for

gal: pixel alignment for Cairo.
gal: pixel alignment for OpenGL

Cleanup of pixel alignment patches

gal/opengl: more pixel alignment patches:
- works on Retina displays now
- pixel alignment for circles
- correct 1-pixel strokes
- fixed unfinished 1-pixel line ends

GAL: Restore antialiasing options in Cairo
GAL: Fix arc drawing

Removes DrawArcSegment, which drew arcs whose edge was optionally
stroked (a feature that we did not use).  Fixes Cairo arc drawing issue
where arcs were not visible in pcbnew.

gal: further cleanup
gal: removed unused shader parameter

Seth Hillbrand 3a3bbbb545 GAL: Add transparency for bitmaps and Cairo draw
Bitmaps loaded via wx can contain alpha channels.  We utilize underlying

transparent highlights

jean-pierre charras 26a337db18 Opengl engine: temporary disable bitmaps cache, because it creates serious issues in cross-probing in hierarchies.
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.

Maciej Suminski 64da77538f Fix bitmap scale in printouts
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 mode and OpenGL mode should have a similar look.
