This is inconsistent with all other fill types, which don't
have a special outline subsymbol. Users should be creating
outline layers when they want an outline instead.
When reading an SVG fill symbol layer from XML, automatically
upgrade any outline subsymbol which is used by the fill to
be separate symbol layers for the parent fill symbol so
that existing symbols will appear as designed in older QGIS
versions.
Fixes qgis#14103
This optional setting allows each point to be randomly shifted up
to the specified maximum distance in the x/y directions. Maximum
offset can be set in mm, points, map units, etc OR "percentage"
(which is percentage of the pattern width/height)
An optional random number seed can be set to avoid patterns
jumping around between map refreshes.
Data defined overrides are also supported.

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.

Fixes#37825
expressions instead of raw expressions
We can greatly simplify the code by doing so, as all the handling
of preparing and optimising QgsPropertys are done automatically
for symbol layers.
Instead we should ALWAYS use the provided points for rendering symbol
layers, or the symbol layer will be broken in various circumstances
(e.g. when used outside of a vector layer)
Fixes#45028
Usually a geometry generator expression must return a geometry
in the associated layer's CRS. But this doesn't work in situations
where a geometry generator symbol is NOT associated with a layer,
e.g. when used in a layout item.
So add a new option to allow users to specify which unit the expression
will return geometries in, with choices of map units (the default,
previous behavior), millimeters, pixels, inches and points.
When millimeters, points, inches or pixels is selected then
the @map_geometry variable will be available for the expression,
and contain the feature's geometry in the specified units (relative
to the map frame). (The $geometry variable remains available and
still in layer CRS, in case an expression needs to calculate the
original area, perimeter, etc in real-world units while returning
results in a different unit!)
A step toward fixing #39159
Gives a means of setting the reference scale for a vector layer
renderer, so that symbol sizes in the rendered layer will be
scaled accordingly depending on the actual scale of the
rendered map.
QFlags created from enum classes aren't automatically converted
from an int value passed by Python code, so we need to create
compatibility functions for the older variants which accept
plain ints
should use symbol levels whenever that symbol is used by the renderer
Not exposed to users -- only settable via API, but IS saved in the
symbol's XML definition and restored when loading a symbol from XML.

- Add enums to qgis.h instead of qgscoreenums, so that they belong to
a Qgis namespace
- Split up the various symbol headers into multiple files so that we
can fine-tune their inclusion and forward declare more readily, speeding
up recompilation
- Move QgsSymbol enums to qgis
Many MapInfo line symbols don't translate well into OGR styles, so
in order to improve the quality of the conversion this commit introduces
a new QgsMapInfoSymbolConverter class which contains utility functions
for converting MapInfo symbols by ID to their QGIS equivalent.
Implemented for line symbols only for now.
