Param's enabled for x and y in gani's.

[grim_squeaker_x]

Currently you can't use any of the Param's for setting a x or y location of a sprite in a gani, while the needed use of it would be rare it could for example be used for a bird which changes it's height while flying without having to resort to showimg for either the bird or the shadow (Which would be better since showimg can lag)
