BREAKING CHANGES

• This is a complete rewrite of the panzoom library
  to be a standard JS lib that doesn't rely on jQuery,
  but can still integrate as a plugin

Fixes compatibility with jQuery 3.4+

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.

Pinch zoom bug fix on mobile devices

• Fixed an issue where a pinch zoom was not recognized unless both fingers touched at very nearly the same time. This should make it much more flexible. You can add a finger at any point during the gesture and both touches will be recognized.

See #270 for more info.

Account for text-align, add back pointer events

• In 3.1.0 (see 20aa64a), I greatly simplified the contain logic. The complexity had piled up to the point where I didn't even understand it all. Unfortunately, I made a significant error and broke all panzoom elements that weren't display: inline with text-align: center–like the ones in the demo page. This patch adds back the logic necessary to contain elements that are not already centered. Note: Panzoom does not support text-align: right. Just set it to left or center.
• I had also removed support for pointer events, but I broke panzoom for devices that have both a mouse and touch support (for instance, some Windows laptops). While Pointer Events can be problematic to support in IE10, IE11, and Edge, I was able to work around all of the problems that have been reported so far. Pointer Event support is now better than ever!
