Currently, we pass the frame duration as a QgsInterval and use the average
duration of a month or year during the animation, for instance, 30 days
rather than a month. This makes it impossible to have an animation that
displays on a particular day each month, as the day in the next month will
change depending on the number of days in the previous month.
This changes QgsTemporalNavigationObject to take the time step and time
step unit as separate arguments. The settings in
QgsTemporalUtils::exportAnimation are left unchanged, because in this case
the user interface is already set up to use an interval.
If the time step has a fractional value, the frame duration is calculated
using a QgsInterval as before. If it has an integer value, the calculation
uses QDateTime to advance by the specified time step instead. So a value of
1.5 months results in a frame duration of 45 days, but a value of 1 month
will result in a duration that depends on the length of the current month.
Fixes#37829.
This renderer merges (or unions/dissolves) the line or polygon features
from a layer prior to rendering them. It's useful for rendering
a polygon layer with overlapping features as one single "coverage" feature,
or a line layer consisting of many smaller component line features
using a regularly spaced marker line or similar.
Internally, this just moves the guts of the existing inverted polygons
renderer to a new base class, as that renderer already had an option
to merge features prior to rendering. Basically it just exposes a new
renderer to users which is the inverted polygon renderer without
the inversion step!

layer, so that these renderers are always drawn either above or
below the normal layer renderer
This allows programatic creation of extra styling for a vector layer,
e.g. to overlay custom markers or outlines on features (such as
highlighting "good" or "bad" features), without messing with
any user-created symbology for the layer.
This adds api in the provider gui to allow a provider to create a custom
widget which exposes options to customise and change the layer's source.
E.g. a file based layer provider could expose a widget for selecting
a new file path, and an online one could expose widgets for changing
the host, authentication, etc.
