Comment:

 This was an issue for all the sprites in all the games that use the
 OPT_PIXPERFECT option. This option tells AGS to look at the sprite
 transparency to detect if a given position is on a sprite. Without it the
 position is on the sprite if it is inside its bounding box. But with the
 option is also checks that the cursor is not on a transparent pixel of the
 sprite. However in ScummVM we were not correctly handling the alpha
 component of the mask color, resulting in the sprite transparency check to
 fail.

 This is fixed in 180d364.
