Module Name:
       download.c

Abstract:

   Functions associated with downloading fonts to printers.  This
   specifically applies to LaserJet style printers.  There are really
   two sets of functions here:  those for downloading fonts supplied
   by the user (and installed with the font installer), and those
   we generate internally to cache TT style fonts in the printer.


Environment:

    Windows NT Unidrv driver

Routine Description:
    This routine download the secondary soft font. If the True type font has
    more Glyphs that what we can download in soft font then we download a
    secondary font after we use all the glyphs in the current soft font. This
    function also sets the new soft font index(pFM->ulDLIndex) to be used.

Arguments:
    pPDev       Pointer to PDEV
    pfo         The font of interest.
    pdm         Individual download font map element

Return Value:
    TRUE for success and FALSE for failure

Routine Description:
    This function downloads the font and the glyphs. If the font is
    already downloaded, it uses that. It goes through all the glyphs
    and downloads the new one. This function also intializes pfm, iFace
    and apdlGlyph members of TO_DATA.

Arguments:
    ptod    TextOut Data pointer to fill the DLGLYPH array.
    pstro   The "width" of fixed pitch font glyphs.
    piRot   Rotation angle in multiple 90 degree.This is output param
            and used by textout call to set the text rotation.

Return Value:
    Download font index if font is/can be downloaded; else < 0.
    The index is 0 based, i.e first downloaded font has index 0.
