Oggetto: Change order in which KonamiGX sprite offsets are applied

this allows the soccerss sprites to not clip at the edges due to offset we apply  (there is still 8 pixel clipping, but this is part of the game and should be hidden by a missing part of the text layer)

note, I haven't tested other GX games, if it breaks you get to keep the pieces because the achocode in machine/konamigx.c  (which really should be video/konamigx.c ...) is impossible to follow*

*  it contains actual operations in if statements, extensive reuse of 'temp' variables for 200 different meanings to save creating a new variable, pseudo asm code, and arbitary sized buffers to do sorting, and code which generally makes no sense at all.  99^ of it iv video related reimplemnetations of konamigx.c with no safety checking and hacks for gx system.
