[FEATURE] Add with_variable function
...
This function sets a variable for parts of an expression, therefore
avoiding to repeatedly recalculate complex values.

Algorithms don't have to be split to prepare/process/postProcess
...
Since it's safe to evaluate parameters in background threads
now, it's usually going to be ok to evaluate everything in
the processAlgorithm step.
This keeps the algorithm code as simple as possible, and will
make porting faster.
Note that the prepare/postProcess virtual methods still exist
and can be used when an algorithm MUST do setup/cleanup work
in the main thread.

[needs-docs] New gui widget QgsFontButton

A standard widget for configuring text format properties for use
with QgsTextRenderer/QgsTextFormat.
It's modelled heavily off QgsColorButton, and supports lots of nice
things like dragging formats between buttons, copying and pasting
format settings, dropping colors from color buttons, dragging colors
from font buttons to color buttons, directly setting font size
and opacity/color without having to open a dialog.
