Whilst usually this is bad practice (reusing an existing expression context),
and instead you should make a new context for every batch of expression evaluations,
we can't do this in the style model and we end up potentially creating
thousands of new contexts. So instead, we use a single one, which is
safe because the actual expression context used here is a very
basic one...

Adds:
- __len__ : returns number of symbol layers in symbol
- [ ] getter: returns a specific symbol layer, also allows negative indices to retrieve from end of symbol
- del [ ]: removes a specific symbol layer, also allows negative indices
- raise IndexError when an invalid symbol layer is requested
- allow iteration over symbol layers using
for layer in symbol:
print(layer.color())
For the c++ api dox this expands to "\c nullptr" (the
\c directive indicates a code literal value), and for sipify/Python
it expands to ``None`` (`` is sphinx annotation for literal values)
Makes for nicer dox for both c++ and Python!
This new option, available under the "Advanced" button for fill symbols,
allows forcing rendered polygons to follow the standard "right hand
rule" for ring orientation (where exterior ring is clockwise, and
interior rings are all counter-clockwise).
The orientation fix is applied while rendering only, and the original
feature geometry is unchanged.
This allows for creation of fill symbols with consistent appearance,
regardless of the dataset being rendered and the ring orientation
of individual features.
