The only thing I can think of (aside from getting the MC folks to build true
bitmap or color based collision detection into MC) is to use hidden polygon
images that act as the "live regions" of your animation (instead of the
rects of the images) and test for intersection of these with your jump
object. You'll need to swap or move multiple polygons in sync with your
animation and make sure you test for the correct number polygon intersection
with the jump object.
Keep in mind, all you really need to test for are extreme edges of the horse
-- you don't need elaborate polygons, probably just rectangles that are
positioned at the outermost edges of the animation.
