csi: the CSI-t family of queries now report unscaled pixel values

Browse source 
Before this patch, we reported scaled pixel values. This was rather
useless, since applications have no way of getting the scaling factor,
to "scale up" e.g. images.

Furthermore, the most common use of these queries are probably to
calculate the dimensions to use when emitting sixels.

Closes #1643
