MOHAWK: MYST: Fix drawing the Stoneship red page open door

When the lights are on, the open door image would not draw at the
correct position in Myst ME only.

This is due to the open door image being too small. The original has a
special case for that image. We reproduce that same hack.

Fixes Trac#7143.
