Both versions of EDA_DRAW_FRAME::isBusy have a useless const_cast.
GetScreen() const returns a non-const SCH_SCREEN already, it doesn't
need to be cast, and it's stored in const SCH_SCREEN anyway.
Move repeated GAL config reading routines into GAL_DISPLAY_OPTIONS.
THe app-level config is in here already, do the same for the
common config.
This means that the configs are loaded consistently, which fixes
the symbol-chooser preview window, which previously didn't use the
same config routine as other GAL canvases.
Future work could move these functions to free functions that
act on the public interface of GAL_DISPLAY_OPTIONS to avoid
GAL_DISPLAY_OPTIONS having to know about wxConfig and wxWindow.

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).

When prompting for a new footprint library, we need to treat the input
as a file for creation rather than a directory for selection.
Otherwise, users cannot specify the name of their new footprint library
independently of the existing directory names.

The config was saving a canvas type EDA_DRAW_FRAME member not always accurately initialized.
And the last canvas opened frame setup was saved, not necessary a frame having a canvas type that can be set by user.
This is a broken feature especially because the footprint viewer has a fixed canvas setting.
The canvas type might change without the frame being notified. If this
happens, the user is presented with repeated notifications of OpenGL
issues. Howver, switching canvas is not an error and should be
presented to the user as an info message to clarify that the system is
still working but it has changed how it renders the screen.

The standard DIM() macro was not typesafe as it happily deferred errors
to runtime that can be caught at compile time. Replacing it with a
generic C++11 constexpr allows for typecasting, comparison and compile
time error checking.
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.
Currently, GAL is initialised to NONE (i.e. off). This causes
issues when Legacy canvas is broken (i.e. GTK3).
This changes the default to GAL Cairo, both in PCB_EDIT_FRAME
init, and in the config load.
Now, when the user starts with no config, they are prompted for
a choice: OpenGL or Cairo, and one of them will be set up, with
Cairo as fall back.
Users on platforms that still support legacy can go to it as normal
from the menu, but it will not be the default in any circumstance.

wxChoice centers the selection on GTK. So when switching from a
mid-list item to an item at the top, the list is always cut off for
choice lists located on the top toolbar. Using a combobox provides a
drop-down that allows easier access to all elements in the box.

This make the use of legacy canvas on GTK3 a default-off
advanced config. Legacy is substantially broken on GTK3
and is of basically no use at all to general users on this
platform.
If the program starts with legacy canvas in the config,
it is forced into a GAL mode, as otherwise it could happen
that the user is stuck and unable to get into pcbnew to change
the setting.
