Change the functions to operate in float and add the
QPoint versions as overload calling them. This is
more in-line with the event accessors using float
and allows for removing some workarounds using a delta when
converting touch points.
Leave QPlatformWindow::map(To/From)Global() as is
for now and add helpers for float.
