If a Scroll event is skipped, a default handler is fired by wxWidgets.
This default default handler fires 3 wxEVT_SCROLLWIN_LINEUP or wxEVT_SCROLLWIN_LINEDOWN events.
This is not wanted now in eeschema (and pcbnew) because they add extra (unwanted) scrolling.

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.
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.

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.
In the previous version the method did not work correctly
when an action was invoked from context menu. In such case,
the cursor position was obtained in the moment of selecting
the action, instead of using the right click location.
