Summary: UPDATED: Fix IE memory leaks in drawview
Bugs Fixed: LPP-7939 - Huge memory leak in IE7 on each reload of the app
Technical Reviewer: [email protected]
QA Reviewer: mdemmon
Details: Tucker fund an updated memory leak checker that pinpointed a
couple of properties in drawview (one in excanvas) that were causing
apps to leak.
Implemented destroy() to clean up after the canvas, added instance to
LzSprite.prototype.__sprites hash so IE cleans up onbeforeunload - see
LzSprite.js for more. Test to be sure __LZcanvas exists before touching
it, delete self from __sprites so destroy isn't called twice.
Tests: test/extensions/drawing.lzx?lzr=dhtml&lzt=html (and webtop) show
no leaks with the leak detector from M$, found at
http://blogs.msdn.com/gpde/pages/javascript-memory-leak-detector.aspx
