For the record, that went into WineX/Cedega internal CVS long before
that, and had already been in a Cedega release by that time. It just got
merged into external CVS where you could see it much later, since active
development is no longer done in the externally-visible CVS. As it
predated your patch by a large margin, it's in no way based on your
work; generally I don't even look at Wine and its patches anymore. The
game it fixed was City of Heroes (rubberbanding effect, where you would
snap back to where you were when you move, and also, mouse clicks were
registered erratically - sometimes as doubleclicks, sometimes not at
all), and the patch was written after consulting some helpful CoH
developers about the problem.

Was planning on implementing something of the sort soon, haven't had
time yet.

Could write a kernel patch and/or module ourselves too... but I don't
feel that's the way I would want to go anyway.
