Fix T96243: Workbench Curvature not rendering in background.

When rendering using the command line the curvature wasn't rendered. The reason
was that the ui_scale wasn't initialized and therefore the same pixels where
sampled to detect the curvature. This is fixed by setting the ui_scale to 1 for any
image render.
