This is the first step to allowing non-segments in the line chain.
External routines cannot be allowed to change the line chain without

On Windows, a sdt::string cannot manage a filename, unless using

So the best way is to use a wxString for filenames and error messages.
The pointer passing for display options is deprecated. This removes the

All requests for display options are now returned const and are updated

In Gerbview, this resolves an issue where the display options were not

The problem is that wxEVT_CHAR_HOOK doesn’t do the key translation
properly. wxEVT_CHAR does, but we only get to that if we skip the
event at the end of the tool’s event processing loop, which most tools
don’t do. (Selection tools, point editors, pickers, and a couple of
others do skip, which is probably why this didn’t get reported earlier.)
I played around with a couple of ways to fix wxEVT_CHAR_HOOK. Most of
them don’t work, and the few egregious hacks I tried weren't cross-
platform.
So I’m changing it so that most tools now skip at the end of their
event loops. I left out a couple that I felt were high risk (length
tuning, for instance). But there’s still enough risk that I’m 100%
sure it will break something, I just haven’t a clue what.

Previously, for instance after modifying preferences or language,
they were rebuilt but the tools state was not set due to a missing call to SyncToolbars() after rebuilding.
Includes the addition of an onSetCursor() handler which must be called
from both the GAL canvas AND the GAL backend (at least on OSX) to prevent
cursor flickering between (for instance) pencil and arrow.
Also includes new architecture for point editors which allows them to
coordiate cursors with the editing tools (so we can switch to an arrow
when over a point).
We were running into various corner conditions where a tool's event
loop would exit while the tool was still active, or the tool would
get popped while we were still in the event loop. (A lot of these
had to do with the POINT_EDITOR's, but not all of them.)
The new architecture:
1) tools always do a Push()/Pop()
2) everyone is responsible for their own pops; no more stack-clearing
on a cancel
3) CancelInteractive events go to all tools to facilitate (2)

If a tool called something like clearSelection while processing a

up processing the click by multiple tools.

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.
THese library do still use common code (including bitmaps,
via base_screen.h) and this allows them to pick up the libcommon
includes correctly.
Use the AddFileExtListToFilter() to also generate the
wildcard for "all files". This is because:
* Users can use AddFileExtListToFilter for the all files WC
with the same interface as for any other extensions.
* Users do not need to worry about wxGetTranslation, as the
_() is applied in the same way as the other *Wildcard() helpers,
and it is a function just like the others, so it is consistent
* There is a testable interface to document the expected result.
The test is added.
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.
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

Major cleanup of many icons (started as a simple effort to tweak libedit and modedit icons)
Ref: https://lists.launchpad.net/kicad-developers/msg32860.html
* Each application icon has been updated
* Consolidated icon "modifiers" across many icons
* Replaced confusing arrows with "load" and "save" icons
* Slight code updates to reference correct icons
* Consolidate multiple representations of single icon type(s)
This is meant as a stopgap for 5.0, with plans to add proper scaled
icons in the 6.0 cycle. A function KiScaledBitmap() is added, which
works like KiBitmap() except it scales the bitmap according to the
calling window's font size. Controls have been added to all the main
applications to let the user select scaling manually (these were omitted
from smaller apps that didn't already have a place to put them).
In addition, in eeschema only, the pixel height of the system font is
shown in the options dialog for diagnostics. This is only for collecting
feedback before 5.0 release from users with different displays and will
be removed.

The GTK+ file dialog is case sensitive however it does support regular

This code adds a method to convert file extensions of any case to the

all file extension case combinations will show up in the file dialog.
A note to developers: make sure to add a file extension when setting
when setting the default file argument. If you do don't set an
extension, the GTK+ file dialog will happily append the regular
expression as the file extension which is surely not what you want.
There are still a few known places (mostly gerbview) where there are
some complex wildcard code that has not been converted.

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).
The introduces INDICATOR_ICON, which is a very simple class holding a

The ICON_PROVIDER class then provides icons to INDICATOR_ICONS, which
means the class can be used for more than just row indicators.

eeschema now supports arbitrary colors for all object types, and
pcbnew does in GAL canvas. When switching from GAL to legacy canvas,
pcbnew will convert colors to the nearest legacy color.
bitmaps.h was included in nearly every file in the project due to it
being included by base_struct.h
Only about 130 files actually use the XPM definitions defined there, and
many of those already included bitmaps.h themselves, or via

rebuilt files for pcbnew alone.
This commit moves the bitmap-related types like BITMAT_DEF out to a new
header, which is still included by base_struct.h, which is less
avoidable for now, it's it's used in the interface.
The icon list is still in bitmaps.h. This has the side effect that's
it's now easier to automatically generate this file.
