point pattern fill
A new option exposes the ability to clip markers in the fill by:
- "Clip to shape": default behaviour, same as previous versions. Markers
are clipped so that only the portions inside the polygon are visible
- "Marker centroid within shape": only markers where the center of
the marker falls inside the polygon are drawn, but these markers
won't be clipped to the outside of the polygon
- "Marker Completely Within Shape": only markers which fall
completely within the polygon are shown
- "No clipping": any marker which intersects at all with the polygon
will be completely rendered
The clipping mode can be overridden via a data driven expression if
desired.

Just like the 'rotate' function, 'scale' accepts an optional point
to apply the scaling from. If not specified, scaling is done
from the centre of the geometry's bounding box.
along a geometry
The new expression functions are:
- triangular_wave: Constructs triangular waves along the boundary of a geometry.
- square_wave: Constructs square/rectangular waves along the boundary of a geometry
- wave: Constructs rounded (sine-like) waves along the boundary of a geometry
- triangular_wave_randomized: Constructs randomized triangular waves along the boundary of a geometry
- square_wave_randomized: Constructs randomized square/rectangular waves along the boundary of a geometry.
- wave_randomized: Constructs randomized curved (sine-like) waves along the boundary of a geometry
along a geometry's boundaries
also includes variations on these which allow for randomized
triangle/square/sine-like waves, with amplitude and wavelength
