When drawing segments that are smaller than the segment width, OpenGL
did not use realistic values, leading to hidden, small tracks. Instead,
we set the track to only draw a segment when the length is at least 1
radius long (so that we can see the full semi-circle at the track end)

In some cases it was not working well.
Opengl was using an other algo (using the curve properties to create segments)
Now only the OpenGL algo is used,
with optimization to reduce the number of segments.
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).

And filled but we don't use those yet. No pixel-alignment needed for
stroked semi-circles (I think) as we set the pixel width to be 1
regardless of the zoom level.

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
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
Fixes: lp:1809845
* https://bugs.launchpad.net/kicad/+bug/1809845
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.
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.
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.
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
wxGLCanvas::IsDisplaySupported() handles wxGL_{MINOR,MAJOR}_VERSION
attributes only in 3.0.4. Since 3.1.0 the attributes are apparently not
supported, so instead wxGLContext::IsOK() is used (introduced in 3.1.0).

In Cairo mode, this function uses already the alpha color value setting.
Now for low alpha values (usually they are low, as said in many GAL comments),
Cairo mode and OpenGL mode should have a similar look.
