[Spice-devel] [spice-gtk] fix check for 16 bit cursor mask

[Frediano Ziglio]

The size was computed using a 32 bit image while the cursor was
just 16 bit. This caused the usage of some invalid bit mask (the
bit mask is used to understand where the cursor is transparent).

This was tested with a Windows XP machine with a working
QXL driver and some color pointers without shadow.
Before the patch the trasparency of the cursor were
wrong.
