Speed up and extend #px to be conveniently used for #scaleFactor support of magic (pixel-based) numbers.
=============== Diff against Graphics-mt.543 ===============
Item was changed: ----- Method: Number>>px (in category '*Graphics-scale factor') ----- px "Convert the receiver representing raw pixels at 100% (96ppi) to the current scale factor. Note that you currently have to do this manually for all graphics-related properties and layout-specific measures such as #borderWidth: and #layoutInset:. Only for model windows (see #initialExtent) that are no dialogs, that scaling will happen automatically in ToolBuilder."
