I don't think this was the original intent, but the
GUI for setting the flag leaked out via the
properties inspector so it kind of needs to work.

This means that an early return or an exception between
a manual Push/Pop (or an omission of the Pop) cannot
corrupt the layer stack.
It also means the GAL doesn't have to maintain its own
stack (with the in-scope GAL_SCOPED_ATTRS taking that role).
Reomve the Push/PopDepth functions, as they're only ever
used in pairs, and doing it manually needs more care.
Moves the logic into the SCH_RENDER_SETTINGS, rather than
repeating it in EESCHEMA/SYMBOL_EDITOR_SETTINGS (they still
maintain their state there, but the painter looks at the
SCH_RENDER_SETTINGS).
Also turn them off for preview purposes.
This makes it easier to see which pins have alt modes
available. There is an option to turn them off.
The icon positions are chosen so they they shouldn't
interfere as far as possible:
* If the text is inside, the icon goes more inside
the body
* If the text is above/below the pin, it goes away from
the body
This means it won't collide with a symbol wall in
most cases, but some symbols with alt pins on opposing
sides may need to be widened if the icons are show.
Includes a rather fiddly refactor of the SCH_PIN painter
function, which needs quite a lot of massaging to allow
it to figure out where an icon would go. Quite a bit
of logic is broken out into smaller encapsulations with
less visible state to each chunk.
Icon modes for base-name-selected and alt-selected are
included, but only the former works due to information
being thrown away during the SCH_PAINTER tempPin
process.

Overriding the color in draw() throws away the alpha that was set
due to aItem->IsSelected() in getRenderColor().
Instead, get the layer BG fill color in getRenderColor() before
the translucency is applied.
Includes:
- Fix GAL to draw closed polygons in eeschema
- Add functionality to eeschema to draw arbitary polygons
- Update polygon item previews to have customisable edge colour
- Add new SCH_RULE_AREA class, derived from a poly SCH_SHAPE
- Add SCH_RULE_AREA to paint and plot methods
- Add new rule area color preference to themes
