Graphic shapes (excluding text) can now have nets when on
copper layers. Shapes behave like tracks in that they will
pick up nets from connected pads, and follow track opacity
settings.
1) Unify metrics between stroke and outline fonts
2) Unify handling of rotation and mirroring
3) Bug fixes in collision handling
4) Use of VECTOR2I (instead of VECTOR2D) for world-coordinates
5) Generate outline font overbar with rounded ends and fix rotation
bugs
6) Generate wxEVT_CHOICE events from FONT_CHOICE::SetFontSelection
7) Change text-item PNS SOLIDs to use compound shapes
New strategy isolates all draw/don't draw decisions to the ViewGetLOD
routines, and all dimmed/not dimmed to PCB_RENDER_SETTINGS::GetColor.
The actual drawing in PCB_PAINTER is more-or-less conditon free.
Also adds new layers for pad and via hole walls so that they can be
controlled for high-contrast mode.
Also changes the drawing paradigm so that the pads are drawn even when
not on the high contrast layer, just in low contrast. The hole wall
is drawn in high contrast. This actually makes things clearer to the
user (although to be honest was done to keep from having to re-render
pads when the high contrast layer changes since we have two separate
layers now that we can adjut colours on).

List of hidden nets stored in project local settings
Hide/Show actions in context menu only for now, will
add them to some more GUI places soon.

LoadProjectSettings changed to take place after the board
has been loaded so that board-specific project settings can
be applied (such as net visibility and color overrides)
LAYER_VIAS needs to get set for them to print at all, and GetLOD
needs too look at the view layer visibiilties, not the board layer
visibilities.
Also implements a more pad-like strategy for printing blind/buried
vias when printing one layer per page (where the top/bottom arcs
don't make sense).

Move the camera out to its own so that everything else is board-
related, and then rename BOARD_ADAPTER.
At some point the flags should probably be moved out too, and they
can have the EDA_3D_SETTINGS name.
