[OpenLayers-Dev] Switching between base layers with different projection?

Hi all,
Sorry for my late reply on this, but I've just finished my school
exams for this year, so have been a little short on time.
Yes, as noted in IRC, I have roughly got this working in a sandbox
(sandboxes/edgemaster/), it reprojects the centre point on layer
change and also any vector layers currently displayed.
As yet, there's no example in the sandbox itself but the code is
working on a few toys I've been developing outside the sandbox.

Over the next few weeks I'll read over all my changes and polish off
the rough edges. I'll also add an example to show what it does.
I also want to look and see if I can do anything with about
reprojecting WMS layers (which is outside of what I currently know

Hope this helps, feel free to ask any questions,
Thomas Wood
