* ScriptStringOut (USP10.@)
*
* This function takes the output of ScriptStringAnalyse and joins the segments
* of glyphs and passes the resulting string to ScriptTextOut. ScriptStringOut
* only processes glyphs.
*
* Parameters:
* ssa [I] buffer to hold the analysed string components
* iX [I] X axis displacement for output
* iY [I] Y axis displacement for output
* uOptions [I] flags controling output processing
* prc [I] rectangle coordinates
* iMinSel [I] starting pos for substringing output string
* iMaxSel [I] ending pos for substringing output string
* fDisabled [I] controls text highlighting
*
* RETURNS
* Success: S_OK
* Failure: is the value returned by ScriptTextOut
