NAME
    IntuiTextLength -- Return the length (pixel-width) of an IntuiText.

SYNOPSIS
    Length = IntuiTextLength( IText )
    D0                        A0

    LONG IntuiTextLength( struct IntuiText * );

FUNCTION
    This routine accepts a pointer to an instance of an IntuiText
    structure, and returns the length (the pixel-width) of the string
    which that instance of the structure represents.

    NOTE: if the Font pointer of your IntuiText structure is set to NULL,
    you'll get the pixel-width of your text in terms of the current system
    default font.  You may wish to be sure that the field IText->ITextFont
    for 'default font' text is equal to the Font field of the screen it is
    being measured for.

INPUTS
    IText = pointer to an instance of an IntuiText structure

RESULT
    Returns the pixel-width of the text specified by the IntuiText data

BUGS
    Would do better to take a RastPort as argument, so that a NULL in
    the Font pointer would lead automatically to the font for the
    intended target RastPort, rather than the system default font.
