Drag-moving text elements on iPad generates odd jump

[ThijsVanDerMeer]

Reproducable using a blank Raphael container and adding merely a single text node:

Touch-dragging a text element generates NaN transform results which, in turn, cause the element to be moved to it's original position (where it was added). Using the center marker to move the element does not cause this behaviour, nor does moving it via javascript commands.

The following JSFiddle contains the code which reproduces this problem. The example (or all of JSFiddle / SVG / touch events, not sure) won't work correctly on iPad however, so only use it as a starting point for reproducing the problem. http://jsfiddle.net/XPnDc/1/

I've used the current git head versions of all used scripts as well when testing locally, made no difference.

Thanks for the report. FYI, I won't be able to look into this until I return from my holiday in two months.
