Independent X/Y scaling in GnomeCanvas...

["James K. Wiggs" <wiggs novum-millennium org>]

   After reading through the documentation on affine transforms, I've
come to the unfortunate conclusion that it is impossible to scale the
canvas, or objects within it, independently in the X and Y dimensions.
Am I correct about this?

   The functionality I'm trying to achieve is to have a chart in a
scrolled window which can be "squeezed" and "expanded" so that varying
amounts of the chart are visible, but only in the X direction; the
chart would always be scaled so that its height precisely matches the
height of the scrolled window viewport.  Clearly, I can accomplish
this by having a routine which simply goes through every item on the
canvas and scales its X values or Y values as necessary, but if there
is a way to compose affine transforms to get this effect, it would
obviously simplify the code enormously.

   So, what: a pipe dream?

thanks,
