Re: MathView

I think what needs to be done is as follows:

* fix the unix version of ::glyphBox() to return measurments in logical
units (note that the current version does not even take font size into
account)

* fix the win32 version (currently returns device units)

* fix the plugin to work with logical units; it currently works around
the the numbers returned by the unix function.

All of this is necessary prior to the 2.4 release if the plugin is to be
included.
