New methods in VIEW class: SetTopLayer(), EnableTopLayer() for managing the top layer display.
New method in PCB_RENDER_SETTINGS class: LoadDisplayOptions() for applying display settings like high-contrast, outline display of items, etc.
Pcbnew, layer manager: add option (popup menu) to always keep copper layers not visible but the active layer, even when the active layer is changed.
Usefull for multilayer ( more than 4 layers) PCBs.
Design rules: increase number of vias and tracks sizes
Pcbnew: netlist reader: change from my recent commits to keep netnames in pads for footprints not in netlist
(allow an user to place some footprints by hand, set pads netnames and do not lost these netnames when loading a netlsit)
Fix other very minor issues.
* Correct all user strings and comments for the correct capitalization of
application names according to JP. They are KiCad, Pcbnew, CvPcb,
Eeschema, and GerbView.
* Add a note the the user interface policy about the correct capitalization.
* All header files used to create the PCB common library now compile as
stand alone code. This prevents the need to define them in a specific
order to make source code compile properly. It should also now be
possible to relocate the source code to build the common PCB library
to a separate folder.
In Render, colors shown were the default colors, not the selected colors, when starting Pcbnew or Gerbview,
because colors were not updated after reading the config.
* Fix grid select box update bug on context menu.
* Fix via size and track width select box update bugs.
* Fix layer pair indicator button update bug.
* Fix auto track width tool bar control enable bug.
* Fix via size and track width select status bug in context menu.
* Fix layer select box and layer control widget select bug when current
layer is removed.
* Add virtual function to notify objects derived from EDA_DRAW_FRAME that
the units setting has changed.
* Coding policy class naming fixes.
Pcbnew: fix that prevents loading modules from libraries (footprint name not identified in lib)
Module Editor: Try to fix incorrect printing. Fixed now only for scale 1. Nor working for other scales. (Work in progress).
Gerbview: Known bug: printing not working.
VRML export: Fix incorrect export of 3D shapes rotations when the 3D shape was rotated.
