Under GTK3, the scrollbars fade in and out, causing a cascade of
re-paint events. These cause KiCad to be unresponsive while the repaint
events occur. By default this is 1s fade in 1s fade out but can be
configured by the user/wm.
Area mapping the repaint events to just scrollbar areas will be a good
solution but until/unless that happens the scrollbars in GTK3 are
problematic.
On GTK+3, the zoom events are smaller and faster, so
the trigger the zoom acceleration.
A simple fix is to use the non-accelerated Mac-style
zooming and an appropriate constant. This can be tweaked
further as needed.

GTK3 smooth scrolling is enabled by wxWidgets but not to the exclusion
of normal scroll up/down events. wxWidgets maps these both to the same
scroll handler and will fire them both if they are not handled before
being queued. Testing timestamps allows us to mark and ignore the
dupes.
This is set to GTK3 only for now as it isn't listed as a problem for
other platforms. But it shouldn't cause issues if it is enabled
elsewhere in the future.
The reduces a little bit of WX dependency, and makes
the timing code a bit more type-safe.
Also adds a more testable interface for the accelerated
zoom controller.
This is done to avoid a big chunk of conditionally-compiled code
in the middle of the event function.
Also separates the zoom logic from the WX_VIEW_CONTROLS object
and isolates it in a separate class behind a clearer interface.
Add some simple tests for sane steps on GTK+3-sized scroll
steps.
This parameter defines the working area (full page) size.
The fix is not perfect, because it does not take in account the page size.
However it is similar to the "old" initialization, before Eeschema GAL.
In Eeschema, a reasonable boundary size is used.
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.
Fixes a crash when typing fast in the place footprint filter box.
Also adds a bunch more checking to GAL locking, including making
sure the same person unlocks as locked, and preventing piece-meal
calls (the RAII objects must be used).
When querying the view, we do not want to including items that are not
on layers that are currently visible. This routine is currently only
used by the selection tool (pcbnew and gerbview) and the grid helper.
Both expected this logic but were indifferent to the additional items.

This fixes some warnings on GCC 8.1:
warning: catching polymorphic type ‘class std::out_of_range’ by value [-Wcatch-value=]
catch( std::out_of_range )
^~~~~~~~~~~~
This fix is along the same lines as:
* ff1802d7a "Fix Coverity "Big parameter passed by value" warnings"
We limit the minimum zoom to Z=0.3. Minimum preset zoom level is 0.31,
so 0.3 is only reachable using the mouse wheel. Smaller than 0.18, GAL
does not display properly.

The only required scroll event handler is wxEVT_SCROLLWIN_THUMBTRACK,
which is responsible for dragging the scrolling sliders. One of the
remaining ones is also called when mousewheel is scrolled (MSW only) and
due to that overrides the new view setting with view settings computed
from the sliders position.

Since we are going to inspect every item for these calls, we don't
need to use the RTREE search, which is expensive with high item count.
This results in ~50% improvement in layer switching time in GerbView
when working with a set of large Gerber files.
Gal mode: graphic cross-air cursor moved on items when clicking on & DRC error, like in legacy mode.
Make popup menu shown when right clicking on a DRC error item working.
