I wonder if this has to do with the changes in where the paper size
stuff is initialized.

(On a side topic, how do you use gdb on noweb source? When I try and
run gschem from the src directory, it picks up the proper
"../noweb/blah.nw" path, but the line numbers are off, making it next
to impossible to use breakpoints or single-stepping.)

Another interesting data point:

In 20040111, if I place a single component in the upper-right corner
of the window (new document), there is an invisible box (in world
coordinates) that components seem to be clipped to when the code
determines what the page extents are. In this case, the upper right
corner coordinates are roughly (121000, 76000)

Same thing in 20041228, except that the box only extends to (24000,17600)

In both cases, if the component is mostly outside this box, it will
not be shown during 'zoom extents'. 20040111 is more lenient about
zooming way out (compare the coordinates), which explains the apparent
regression when opening old schematics.

Are any Linux users seeing this issue in either version? I can
reproduce the invisible box problem with 20040111 (same coordinates as
above) using Debian packages, but I haven't built 20041228 from source
on Linux yet.
