/* SYNOPSIS */
AROS_LHA(struct IntuiText *, iText, A0),
/* LOCATION */
struct IntuitionBase *, IntuitionBase, 55, Intuition)
/* FUNCTION
Measure the length of the IntuiText passed to the function. Further
IntuiTexts in iText->NextText are ignored. The length is measured in
pixels.

iText - The size of this text. If iText->ITextFont contains NULL,
the systems font is used (and *not* the font of the currently
active screen !).
RESULT
The width of the text in pixels.
