 Interface to the freetype 2 library.                                 
                                                                      

 Cleanup TTF environment.

 Initialise the TrueType fonts interface.

 Cleanup. Is called by the gCleanupTTF destructor.

 Map char to unicode. Returns 0 in case no mapping exists.

 Get width (w) and height (h) when text is horizontal.

 Compute the glyps positions, fgAscent and fgWidth (needed for alignment).
 Perform the Glyphs transformation.
 Compute the string control box.
 If required take the "kerning" into account.
 SetRotation and PrepareString should have been called before.

 Put the characters in "string" in the "glyphs" array.

 Set hinting flag.

 Set kerning flag.

 Set the rotation matrix used to rotate the font outlines.

 Set smoothing (anti-aliasing) flag.

 Set text font to specified name.
 font       : font name

 Set text font to specified name. This function returns 0 if
 the specified font is found, 1 if not.

 Set specified font.
