Class Description

                                                                      
 TGX11TTF                                                             
                                                                      
 Interface to low level X11 (Xlib). This class gives access to basic  
 X11 graphics via the parent class TGX11. However, all text and font  
 handling is done via the Freetype TrueType library. When the         
 shared library containing this class is loaded the global gVirtualX  
 is redirected to point to this class.                                
                                                                      

 Create copy of TGX11 but now use TrueType fonts.

 Compute alignment variables. The alignment is done on the horizontal string
 then the rotation is applied on the alignment variables.
 SetRotation and LayoutGlyphs should have been called before.

 Draw FT_Bitmap bitmap to xim image at position bx,by using specified
 foreground color.

 Draw text using TrueType fonts. If TrueType fonts are not available the
 text is drawn with TGX11::DrawText.

 Get the background of the current window in an XImage.

 Test if there is really something to render

 Perform the string rendering in the pad.
 LayoutGlyphs should have been called before.

 Set specified font.

 Set text font to specified name.
 mode       : loading flag
 mode=0     : search if the font exist (kCheck)
 mode=1     : search the font and load it if it exists (kLoad)
 font       : font name

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

 Set current text size.
