- 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
Adds data defined control over layout map grid:
- enabled state
- interval X/Y
- offset X/Y
- frame size and margin
- annotation distance from frame
- cross size
- frame line thickness
Fixes#30246, fixes#27737
Adds a new visitor pattern API for creation of visitors which visit
all the style entities (symbols, color ramps, text formats, and
label styles) associated with different objects. Can be used on a
renderer, map layer, or project wide level.
E.g. on a project wide level, allows collection of ALL the style
symbols/color ramps/text settings inside a project, including those
in layouts or annotations!
margin is set
Instead, split this behaviour off into a new "Line border (Nautical)"
grid style. It's a very specific type of effect and won't always
be desirable when using margins with the line border style.
Checks whether a function declaration has parameters that are
top level const.
const values in declarations do not affect the signature of a
function, so they should not be put there.
