[PATCH weston 2/4] compositor: fix weston_output_transform_coordinate

[Derek Foreman]

weston_output_transform_coordinate() was supposed to convert from device
co-ordinates to global co-ordinates.

Commit 0f67941c broke that by converting from global to device instead,
which just magically works ok for single untransformed outputs (where the
transformation is identity)
