Test Energy Skate Park: Basics 1.0.0-dev.75

[samreid]

I published energy skate park basics for dev testing here:
http://www.colorado.edu/physics/phet/dev/html/energy-skate-park-basics/1.0.0-dev.75/energy-skate-park-basics_en.html

This version uses WebGL for the first time on any of our sims, so should be tested thoroughly for rendering issues. You can tell if the sim is running in WebGL mode by looking at the pie chart: if there is a black line between slices, it is SVG. If there is no black line between slices, it is WebGL.

Please test on the following platforms:

Please test it on the following platforms at a minimum:

• Windows + Chrome
• Windows + IE
• OS X + Safari
• iPad iOS + Safari

For the issues marked as "ready for review", please read through the issue and test whether it is resolved. Please comment on the issue and check the box below when you have done so:

• Sometimes the skater is facing the wrong direction on the ground energy-skate-park-basics#181
• Inconsistent behavior with stick to track disabled.  energy-skate-park-basics#194
• Track available bounds was null after reset all. energy-skate-park-basics#201
• With "no-stick-to-track" enabled and overlapping tracks the skater follows the vertex energy-skate-park-basics#238
• Skater teleports after cutting specific track energy-skate-park-basics#239

Please test on IE11 and let me know if you see it slowing down after a few minutes as described here:

• IE11 gets very slow after about 2 minutes energy-skate-park-basics#277

Please comment on IE performance when turning on the speedometer:

• Speedometer needle renders very slowly on my old HP laptop running IE11 energy-skate-park-basics#280

Does the sim speed up and slow down irregularly on Chrome?

• The sim speeds up and slows down on at least one Win7/Chrome energy-skate-park-basics#273

Do you ever see any skater flickering?

• Skater flickers (disappears and reappears 20-30ms later) on moveToFront() energy-skate-park-basics#267

Please comment on your findings in the linked issues themselves, and let me know when testing is complete.

Also, for any other issues you discover, please check to see whether there is already an issue for it before reporting.

Assigning to @ariel-phet to prioritize and reassign.

I've made a number of changes since Monday, and would like to publish a new version before testing begins.

[samreid]

Specifically, here are the commits since dev.75:

• Removed EnergySkateParkBasicsModel.editing, see 'editing' model property is only ever set to false, never read? energy-skate-park-basics#289
• Simplified numerical constant in EnergySkateParkBasicsControlPanel, see energy-skate-park-basics/Numerical constant in EnergySkateParkBasicsControlPanel energy-skate-park-basics#288
• Use {label,icon} instead of [], see EnergySkateParkBasicsControlPanel minor possible refactoring energy-skate-park-basics#287
• Cleaned up formatting in EnergySkateParkBasicsControlPanel.js, see Hard to read code formatting in EnergySkateParkBasicsControlPanel energy-skate-park-basics#286
• If any pie chart slice is too small, then don't show it. Use the same rules as the non-webgl pie chart, see Pie chart should be seamless when only one type of energy energy-skate-park-basics#136
• If the track has translated, hide the buttons, see Scissors and X buttons do not follow moving track energy-skate-park-basics#272
• remove unused "requirejsNamespace' key from all package.json files
• Avoid IE WebGL software renderer, see IE11: Temporarily switching to software rendering to display WebGL content. scenery#285

I'm going to close this issue and will open a new issue when dev76+ has been spot tested and published.
