- The Frames list shows the drawing's frame state (hide / display and plot /
display but not plot / frames vary), follows commands, undo and document
switches, and lists the mixed state as a disabled item.
- DWFFRAME and DGNFRAME are frame variables of their own, kept in the header,
and FRAME sets them with the others.
- Out-of-range frame values say "Requires an integer between 0 and 2." and
ask again; a set value reports "Regenerating model.".
- IMAGEFRAME is stored in the image variables as bits (2 is written as 3) and
a drawing without them uses the profile value, which setting IMAGEFRAME
updates and the settings file keeps.
- Raster images, PDF underlays and wipeouts are picked on their frame only;
underlay snap geometry is never picked.
