Seth Hillbrand db0523626c GAL: Deal with thick circles
Both Cairo and OpenGL had issues (different, though) with circles that are
thicker in line width than they have radius.  This corrects the OpenGL
implementation (radius is calculated to the outer edge) as well as Cairo
(line width needs to be clamped to twice the radius)

jean-pierre charras 8ad15b1d66 Symbol editor: fix issues related to axis not shown.
In Symbol editor, axis are always shown. However after switching the backend, axis were no longer drawn.
In Cairo engine, fix a bug preventing axis to be shown.

Seth Hillbrand 82cbe9c995 cairo: Don't adjust grid point size
We shouldn't adjust the pixel size of the grid based on alignment in
GAL.  This creates artifacts on the screen at different zoom levels.
The pixel width is fixed by grid size preference

Also clean a left-over debug statement

Seth Hillbrand 2305c5458e cairo: Prevent arch shaking in pcbnew
Arc pixel adjustment needs to be limited to +/-1 pixel.  But making this
adjustment to nearby points and then using the projection to correct the
center point accumulates errors that are large for angles near 0 and
near 360.  This is a compromise that aligns _most_ arcs and provides
stable generation for all angles.

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.

Seth Hillbrand e8333633fe GAL: Add antialiasing options to Cairo
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.

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.

resized.

Maciej Suminski ddf4f3b2bc Remove not used cursor fields & methods in Cairo GAL 2017-03-22 10:37:43 +01:00
John Beard b8edecc10f Move cursor shape flag into GAL settings
The motivation here is to concentrate display options in the GAL display
settings, ready for removal of legacy canvases. Instead of having the
property as a member of the DRAW_FRAME, with the GAL canvas retreiving
it from there, it is now in the GAL_DISPLAY_OPTIONS struct, and both GAL
and legacy get it from there.

The options for setting cursor shape are then moved out of the general
options dialog, and into the GAL display options widget, where they can
be used in all GAL-aware programs.

GAL cursor shape works on GAL, but not legacy, so the option is now
available on OSX (but only affects GAL, and is labelled as such).
