I changed mouse event from click to mouse down.
But browser does NOT fire the mouse down event on rectangle svg object.

Need help!

Ok the issue was: we were using openseadragon-2.0 instead of openseadragon-1.0. I've reverted back to osd-1.0 and it works fine now.

I've made this fix in a temprorary branch: https://github.com/camicroscope/ViewerDockerContainer/tree/markdown_mousedown_fix

To get this fix to work we'll need the latest data container not the 0.9

@bridge2014: Can you please test this branch(https://github.com/camicroscope/ViewerDockerContainer/tree/markdown_mousedown_fix ) on 177? Once it's tested we can close this issue and upgrade distro to use data container 0.9.1 and the new viewer code.

how to fix:

From geoJSONHandler.js file, change code from
jQuery(".annotationsvg").click(function (event) {
to
jQuery(".annotationsvg").contextmenu(function (event) {

the ALT key _right mouse click will launch featureScape button.

reverted back to openseadragon-1.0 enable mousedown function , but this version of openseadragon can cause other problem, such as the filter function requires 2.0 or latest openseadragon library.

One of error caught in browser console is:
Uncaught TypeError: Cannot read property 'BRIGHTNESS' of undefined
at osdCamicroscope.php?tissueId=test_1:152

I suggest keeping openseadragon 2.0 library and use alt+ right mouse click solution.

We're using openseadragon1.0 at all the stonybrook instances. The brightness error is due to the filtering feature which we're not releasing in this version. I'll go ahead an disable it completely. As for the right click, lets check it out on the call and decide if we want to go ahead with it.
