Originally opened as adobe/brackets#6697
This is for #6538. This uses the getHoveredEditor() function from@SAPlayer's pull request #6571, so this is a replacement of that PR.
Details:
- only processes mousemove event in
requestAnimationFrame() - defers all processing until after
setTimeout()delay - exception: when Quick View is already being displayed, then processing is immediate
Results:
I did some simple profiling on Win7 using the src/extensions/default/QuickView/unittest-files/test.css file and Process Explorer. I moved mouse over the css rules in that file at an even pace -- so that only mouse processing was executed (i.e. didn't stop long enough to display Quick View).
- Before: cpu averages ~2%
- After: cpu averages ~1%
