I posted a CVS patch to the devel list a while ago which implemented an
alternate image class which could plot data on a stretched (rectangular)
grid much faster than pcolor can.  The patch wasn't entirely complete as
I'm unsure what the user-interface should be but it is usable and does
what you seem to want to do without additional dependencies and with
fast zooming and panning once data is loaded.  I've tested with data up
to 2048x2048 in size and it's quite usable on my laptop.

If you are interested I can give you a patch against the current CVS.
