Summary: Reduce calls to getTextDimension()
Bugs Fixed: LPP-8016 - Performance differences between OL 4.0.x and
4.3.x
Technical Reviewer: ptw
QA Reviewer: hminsky
Details: LzSprite - Clear out additional cache to prevent leaks in IE.
LzTextSprite - Cache lineheight when the CSS value is set directly to
prevent measuring it later. Reuse measurement divs when the style is
equivalent.
Tests: test/lztest/lztest-textheight.lzx?
debug=true&lzr=dhtml&lzt=testboth runs as before, webtop has around
half the number of calls to getTextDimension().
