[PATCH] InsetGraphics updates #2

[Baruch Even]

Adds the scale method as request by Michael.
Fixes the EPS detection part, non hacky revision (Garst please test).

The scale option is added to the horizontal part but affects both
horizontal and vertical, bad UI, I know. Consider this a proof of
concept, and if someone won't do the UI fix I'll do it some other time.
