First, we recently changed the naming convention for XCB 1.0 RC1, so  
the requests are now called xcb_render_composite_glyphs_8/16/32.

Second, we discovered that our XML code generation could not  
correctly support all the types of glyphs, so the parameters to these  
functions have changed from a list of GLYPH unions to simply an array  
of bytes. However, this leaves it up to the caller to convert the  
list of glyphs correctly.

Third, the function you are porting belongs in the xcb/util/ 
renderutil library, named xcb_renderutil_composite_string_8.  A  
useful starting point would be the implementation in the libXrender  
library found here:

   http://gitweb.freedesktop.org/?p=xorg/lib/libXrender.git;f=src/ 
Glyph.c;a=blob

I encourage you to work from the latest git sources.  You can find  
information on working with our anonymous repositories here:

Sorry if this means more work for you.
