From: Christopher Yeoh <yeohc@au1.ibm.com>
The attached patch implements osGetDrawStringSize that looks like: vector osGetDrawStringSize(string contentType, string text, string fontName, int fontSize) in LSL. It is meant to be used in conjunction with the osDraw* functions. It returns accurate information on the size that a given string will be rendered given the specified font and font size. This allows for nicely formatted and positioned text on the generated image.
