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.

Factor out save current canvas view to image file code from symbol editor
code so it can be used anywhere.
Add ability to save to any image format supported by wxBitmapType. See
https://docs.wxwidgets.org/3.0/gdicmn_8h.html#a90a1eb6d85b5044a99b706fd979f27f5.
Currently only PNG output is implemented.
Please note that there is a minor bug that appears to be due to the
scroll bars which causes unfilled areas on the right and bottom edges
of the image. This always existed in the save symbol editor view
image but it was not as noticeable because by default the background
color is white. It is very noticeable in the footprint editor with
a black background.
The usual smattering of coding policy and comment fixes.

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.
Block rotate and mirror now work like they do in Pcbnew (that is
they're treated as part of the block move/duplicate/whatever
rather than finishing it).

1) when duplicating don’t keep original hidden until end of drag
2) reset selectionArea when showing it so it doesn’t flash in its previous location
3) center a pasted block on the cursor
4) don’t draw the source selectionArea when pasting a block
5) implement selection-style highlighting for contents of blocks
6) add pasted items to view so they don’t disappear when the block is placed

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.
Note: it's only the renderer that is changed from wxDC to GAL. Tools stay the same, consider this a temporary hack.
This commit splits the EDA_DRAW_FRAME, EDA_DRAW_PANEL and BLOCK_SELECTOR classes into two variants, each independently compiled into a static library.
- "legacy_wx" for PCBnew/Gerbview - wxDC-based legacy canvas. We have full GAL support there anyway so it makes no sense to introduce GAL rendering API to the legacy tools.
- "legacy_gal" for EEschema and the rest - GAL-based legacy canvas, using legacy tools but with a GAL renderer.
Such split ensures only a small part of the common library and eeschema is affected, without messing around with already GALified tools.
The commit also removes some header dependencies on class_drawpanel.h
