Julien "_FrnchFrgg_" RIVAUD fcadcac7e7 Make knobs size requests dynamic
At the point of creation, the automate_button size request is wrong
since it has not the correct style yet. Instead of trying ugly hacks to
fix that, connect to the knob's size_request signal and get the button's
requisition only when needed. If the system font changes to one that has
different extents (even if the point size is the same), the UI will thus
correctly update.
