If an output is rotated, we will compute a transform matrix for the
cursor plane to rotate its contents.

In order to compute that matrix we need the rect of the cursor in the
device-independent pixels, the scale factor and the output transform.

The problem is that we provide a rect of the cursor in the native
pixels. This may result in the cursor being partially or fully clipped.
