But my controls have no font and do not auto-resize for text (or anything)
It it some sort of internal scaling factor that can be disabled?
It's for a DrawingArea that writes (and rotates) an image, correct size was
kinda needed. (although i figured a workaround)

At runtime if i set the controls to be 128x128 they set that size.

Will i have to set everything manually at runtime if i want to ensure
required dimensions are met?

Many thanks
