video: tegra: Allow fractional input rects
This change makes the input rect for Tegra windows be a 20.12 fixed-point number instead of an integer. This allows software to specify sub-pixel precision. bug 818525 Change-Id: I130f63b68159ed896d1113ea537307997875ca40 Signed-off-by: Robert Morell <rmorell@nvidia.com> Reviewed-on: http://git-master/r/40526 Reviewed-by: Varun Colbert <vcolbert@nvidia.com> Tested-by: Varun Colbert <vcolbert@nvidia.com>
