Comment 8 for bug 448963

I have the same issue with dual screens and I appreciate Fabrice's solution but I have to wonder if it isn't somewhat short-sighted. I can see a use for a much more general solution that doesn't assume simply two monitors side by side.

I'm thinking that what might be best is a set of four floating point numbers to indicate the 'percentage' of the display in each direction to which the tablet should be mapped: starting and ending x values and starting and ending y values. Each value would have a valid range of 0.0 to 1.0 where, for example an x value of 0.0 is the far left edge of the virtual screen and 1.0 is the far right.

Thoughts?
