Subject: VIGS: bind multitouch points to window coordinates
X-Git-Tag: Tizen_Studio_1.3_Release_p2.3.2~334

VIGS: bind multitouch points to window coordinates

It seems a better solution than using guest coordinates
since we no more need to take any special care about
preserving mt points size (i.e. scaling/rotation stuff).
