Dear Jesper Peterson,

yes, the Bifrost library is still being implemented.
In the coming version (v2.0) some of the enhancements that I
can mention is that PostScript output can be generated by most
object/paint type combinations. And besides this, Bifrost 
will be possible to use with the Graphical User Interface 
Library Lidskjalv that we are currently developing.
This will make the process of reating portable applications
with windows, menus, etc. AND object oriented graphics.

Besides this we hope to have all the remaining parts implemented.

We respect to your specific question:
You ask if PixMaps will be implemented. As i recall it, only
readFromPBMFile and writeToPBMfile are unimplemented for PixMaps
at the moment. Is it these two operations you need?

For the Intersects (and Within) operations, it is a little hard
in general to determine if e.g. a Shape (which may have holes)
and an ellipse intersects. Probably the native Region utilities
will have to be used. Is your need to determine whether one
Shape intersects with another Shape?

Sincerely,

Peter Andersen
