[cla] [patch] getTextWidth methods for gfx (vml+svg) text

Description
In IE it is possible to get the text width with: rawNode.style.display = "inline".
In FF and Opera there is the "orphan issue": solved in FF cloning the text node; in Opera (at the moment) with a while loop: the width is valid when takes a value != 0.

Two duplications removed in my previous svg.diff
In vml.js now is dojo.gfx.pt2px(...) instead of dojo.gfx.vml.pt2px(...)

SVG (in FF at least) also supports "getComputedTextLength" on any SVG text element; this returns an integer.

Replying to ttrenka:
Both getComputedTextLength() and getBBox().width have the "orphan issue" http://wiki.svg.org/GetBBox in FF and Opera
No flickering with this solution, because the original node and the cloned node have same position and dimensions

While this is a useful functionality, I am hesitant to update the code, because I don't like modifications of a node directly, or with a measurement node --- it make cause flickering in some cases. We have to make sure that all changes are completely invisible.
