This is a small update to fix an error when accessing jQuery.cssProps, which no longer exists.
Note on next release
There are some known issues that have been in Panzoom for a while, but the rewrite is still in progress. I'll address as many issues as I can, but with everything changing, some old issues will become irrelevant and some new issues will be introduced. I will reopen GitHub issues when Panzoom 4.0 is ready.
