sip doesn't use the standard Python staticmethod type for defining
static methods, which means that standard means of testing
for a static method (like `isinstance(..., staticmethod)`) fail
with any PyQGIS static methods.
This causes issues with lint tools, which incorrectly flag
calls to QGIS static methods as missing self arguments. It also
breaks detection of static methods in the sphinx PyQGIS docs,
so all static methods are shown as non-static.
Work around this in sipify, by wrapping unambiguously static
methods in staticmethod wrappers.
use this as the text format for newly created layer labels
Instead of defaulting to a random font, this gives us a mechanism
to supply a better default label font to users via the default
style database. And users can always modify this "default" text
format if they'd like to change the default font!
For now this is the underlying code logic changes only -- we
don't yet include a 'Default' text format in the default style database
to take advantage of this functionality.
