Great work indeed! Very impressive and well designed. Big +1 here. However
as a rendering/styling/etc... novice I do have some basic api questions.
Excuse my ignorance but in the RenderingTranformation and RenderingProcess
interfaces why do the invertQuery methods meant for vector data take a
GridGeometry? Where does this come from?
Also the invert methods. If I read it correct there job is take a query made
by a user and morph it ensure that it includes the data needed to perform
the transformation? When i see inversion I think of changing something to be
opposite or reversed. IS that the case here?
