1) Generate refreshPreview events so the modern toolset doesn't
fall behind by one event (see LP:1818667)
2) In the legacy toolset don't call unimplemented routines and don't
snap to grid on the non-movement axis.
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.
Put the cursor and pan control TOOL_ACTIONs in ACTION,
and refer to them in that way.
The handlers are currently identical in Pcbnew and Cvpcb,
and Gerbview (and all canvases) can benefit from them as well
if they are in libcommon. Also saves duplicated code.

Add Display Settings to Footprint Browser.
Make each of them OpenGL on OSX and Cairo on other platforms.
Allow auto-zoom to be turned off and save last zoom setting.
Make ordering of tools in htoolbar consistent.
Standardize grid and zoom drop-downs.

Fixes a bunch of errors:
- libedit and libbrowser would zoom to bounding box but centre on canvas
- libedit, libbrowser and gerbview didn’t take the scroll bars into account
- pcbnew didn’t take scroll bars into account or apply the 10% margin
- appending a board file would re-centre, but not re-zoom

- added TOOL_INTERACTIVE::resetTransitions()
- made protected and moved TOOL_BASE::setTransitions() to TOOL_INTERACTIVE
- TOOL_MANAGER calls TOOL_INTERACTIVE::resetTransitions() instead of
setTransitions()
A new items is added to the GAL display options (and the dialog), and a
hotkey (Ctrl+Shift+x) is added to toggle it.

BOARD::GetBoundingBox() now directly calls BOARD::ComputeBoundingBox()
and there is a new method BOARD::GetBoardEdgesBoundingBox() used for
call sites that needed to use ComputeBoundingBox( true ) in the past.
This allows COMMON_TOOLS to implement ZoomFitScreen without knowledge
of the BOARD class.
Some grid/zoom tools are left in PCBNEW_CONTROL because they currently
depend on Pcbnew-specific class members. Once refactoring is done to
make it possible to use all zoom and grid controls outside of pcbnew,
these last tools can be moved to common to match their ACTIONs.
