wxPlatformInfo::Get() causes a linker error on Msys2.
Fix this by making common link wx explicitly, rather
than implicity via it's dependencies, which cause
wrong-order linker command lines on windows.
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).

GTK3 provides for additional input devices via xinput2. These include
touchscreens and continuous scroll devices. But wxWidgets does not have
specialized handlers for these events, so they double up for some
devices. Until wxWidgets allows us to handle these events, we specify
that the input handler should be the old-style GDK_CORE.
GTK3 does a fade in/fade out routine for scrollbars by default. This
was problematic as it caused a cascade of full-screen repaint events on
each mouse event. Instead of disabling scrollbars (which only helped
the full canvas), we force the old scrollbar behavior is environmental
variables.

Libpolygon can provide its own includes via target_include_dirs PUBLIC.
This means any linking targets do not need to specifiy them manually.
As common requires polygon, the polygon dep is also now no longer
required downstream of libcommon, as it's transisitvely implied
by libcommon's target_link_libraries.
This resolves a circular dependency previously detected and also
simplifies CMakeLists.
The bitmap definitions (BITMAP_DEF and so on) do not
have any dependencies on other libs, including WX. This
means the bitmaps library can be isolated from the other
dependencies.
Common now depends on bitmaps, and libraries that depend
on common can pick it up from the common target_link_libraries,
as it is PUBLIC. This means a lot of targets no longer
need manual bitmap linkage.
This avoids a circular dependency that was previously reported
by static analysis.
Avoiding pulling in WX and other headers into the include
tree of each bitmap .cpp is a huge speed up (around 10x) in
compilation, and the generated static library is also 10x
smaller (20MB vs 200MB)
Add common as a link library to pnsrouter,connectivity.

Factor out common dialog code from global symbol library table dialog for
loading initial library table.
Update global symbol library table code to user factored out common dialog
code.
NEW: By default a clipboard is pasted to a grid starting from the
cursor position and doesn't matter is a selection of cells present or
not. Often a grid represents the data of a few similar objects like
components, for example. Some number of cells (fields) may have the same
value for a few rows (components). In this case, when filling data we
must copy the range of identical cells from the first row of similar
components and then paste it to every row of the rest components (by
default). From now it may be done easier. We must copy the range of
identical cells from first row of similar components (here is no
changes) and then select rectangular range of cells (for multiple rows)
where must be placed copied data. After pasting copied cells will be
pasted to every selected row.
So in general, we can copy cells from one row and paste it to multiple
rows at a time.
This new feature also makes possible to copy value from one cell and to
paste it to all from the selection.
If copied range of cells is larger than the selection then only the part
of clipboard that matches the selection will be pasted.
CHANGED: By default dialog closes on Esc key immediately and if dialog
has a grid control there is no way to close a cell editor with canceling
changes. New behavior is next: if dialog has a grid and the grid has an
active cell editor Esc key closes cell editor, otherwise Esc key closes
the dialog.
CHANGED: On pasting multiple rows from a clipboard to the end of a
grid, the grid is automatically expanding (appended needed number of
rows). In general case the grid expanding on pasting is inappropriate.
Rows must be added by tools like a button or a menu command etc. In some
cases rows cannot be added at all. So we must paste only the part of
the clipboard that fits between the cursor position and the end of the
grid without a grid extending.
CHANGED: First click sets a cursor to the specified cell, second click
activates editor (current realization, where first click activates cell
editor, is very buggy especially with cells selection).
Set cursor on cell of reference on mouse left click in Fields editor of

When removing steiner points, there is the possibility that the test

* Sensitive to XDG_CONFIG_DIR, so flipping configs is easy
* Better compiler coverage (less conditionally compiled code means
less chance to break a different configuration). Also better
analysis coverage.
* Type safe config params
* Centralised documentation: it's in doxygen, in one place
No advanced config should be required by a general users. If a general

For now, the config is read-only, and is read from the

The fracture() call may result in zero polygons remaining, which will
