Calculate radius deltas as a ratio from previous geis event

The radius values are scale factors from the geis begin event, so the
deltas should be scale factors from the previous geis event too.

Save position in slice state and calculate deltas based on it

When synchronous events are not enabled, multiple grail events may have
been dropped in between geis events. Before this change, the geis deltas
were based on the grail deltas, which only accounted for the changes
between the previous and the current grail slice instead of from the
previous and current geis event.

This change started off as a reversion of commit 226.1.3, which
introduced the regression. The initial slice state was corrected to
represent the initial position. The number of touches was saved in the
slice state. Then, if the number of touches changes we reset the slice
state. This ensures we still have lp:967267 fixed.
