Title: [Gtk3] fix sizing for different SizeRequestModes

This PR fixes some Gtk3 sizing issues, especially for vertical widgets like Sliders with vertical orientation. Fixes additionally cases when widgets had a zero size initially or min sizes without effect.

* request widget size based on Gtk.SizeRequestMode
* always set Gtk size requests
