tdf#47243 tdf#39327 tdf#103639 Proper scaling of SetPageTransform

Browse Source 
The EmfPlusSetPageTransform record specifies scaling factors and units for converting page space
coordinates to device space coordinates.
In previous implementation I made scaling after translating page scaling.
For some images it was working correctly (if there wasn't translating).
WIth this commit I fixed this issue.
