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 30612ca62d grid: Set grid to use integer pixels
Each dot is an integer number of pixels wide, so supporting 0.5 width
steps no longer makes sense.  We round up the existing settings to the
nearest integer and only allow integers in the dialog.

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.

Jeff Young afeebc8944 Grid settings for Eeschema GAL.
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.

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).

John Beard 78a5185857 Allow GAL cursor to be always displayed
A new items is added to the GAL display options (and the dialog), and a
hotkey (Ctrl+Shift+x) is added to toggle it.

John Beard 8766b475c6 Sanitise incoming GAL config options using mapping tables
When reading config options from files, it's important to make sure the
value makes sense - the incoming data could be anything, and may have
incompatible values or be otherwise unreliable.

This introduces a simple way to define and use "mapping tables" which
can map between a "native" value, probably an enum (but not necessarily)
and some external value, for example the value written to file.

This provides a decoupling between the two values, as well as sanitising
inputs and outputs. This is important, as over time, if there isn't a
decoupled interface, changing options result in corrupt configs, or a
proliferation of obsolete enum values kept for compatibility.

John Beard 0bf3a19967 Add user control for grid minimum spacing in GAL
This allows the user to set a thicker grid line without causing the
grid lines to become over dense, or just make the grid denser according
to preference.

The term "density" is modified to "minimum grid spacing", which is
the pixel spacing between adjacent grid lines.

The spacing settings now comes in along, with other GAL display settings,
as part of GAL_DISPLAY_OPTIONS observer functionality. To this end, the
setter in GAL interface is removed, as an external user should be
setting this parameter via the GAL_DISPLAY_OPTIONS interface.

John Beard 970e4f8eb4 Add grid line thickness control to Display Options Dialog
This adds a user-settable control for the grid line thickness on GAL
canvases to the display options dialog.

The thickness settings now comes in, along with other GAL display
settings, as part of GAL_DISPLAY_OPTIONS observer functionality. To this
end, the setter in GAL interface is removed, as an external user should
be setting this parameter via the GAL_DISPLAY_OPTIONS interface.

John Beard 7ad30b7167 Move Grid style to Graphics Options dialog
This puts the graphical/display options with the other similar options
in that dialog, rather than with the dimension options found in the Set
Grid dialog, which is in the Dimensions menu.

Also place the option itself in the GAL Display Options structure, so it
can be updated using the observer mechanism there.

The setter for the style in the GAL interface is removed, as the public
interface for setting this option is now to modify the
GAL_DISPLAY_OPTIONS structure and notify the GAL when done.
