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.
