Log Message: ----------- GeanyWrapLabel: fix rendering issues
GtkLabel may re-create its PangoLayout between calls leading to the final layout used for rendering not to be set up with the appropriate values for our sizing. Then, re-set up the layout each time we have to deal with it and straight before GtkLabel renders it.
