Optimize drawing of buttons with changing text
When a button has a fixed size, there's no need to call queue_resize().
This fixes an issue with the ArdourClock info displays when slaved.
The Timecode and Delta display text changes in small intervals and
caused excessive CPU load due to GUI size-requests + redraws.
