And it does stay that way. Currently, we have an opacity control in the
transform dialog. This defaults to 100% IIRC. It only effects the *display*
during transform. The opacity setting of the layer is unaffected, it's
simply not in operation during that time.

(There are various logical problems with using the layer's opacity during
transforms... eg, transforming part of a layer -> overlapping parts are
inaccurate, and non-overlapping parts may be inaccurate if the layer has no
alpha channel. Same applies to transforming a whole layer.. because the
original is not, and must not be, hidden during the transform, inheriting
the layer opacity causes problems with the accuracy of the display)
