[Cairo] renaming cairo_concat_matrix

[Bill Spitzak]

Thought I'd try getting this into a new subject.

This is a discussion of how to rename cairo_concat_matrix to use only full 
words in all call names.

How about "transform", ie cairo_transform(cairo_t, matrix). Note: no "matrix" 
in the name.

This matches cairo_translate(x,y), which is not called 
cairo_translate_vector or cairo_translate_xypair or anything like that.

If we want to transform by other types of objects, personally I would like to 
see C++ function overloading added to C. Failing that, it seems the standard 
is to use very short (and thus abbreviated) trailing names to indicate the 
argument types. For instance OpenGL has all the 2f, 3d, 4i, etc type suffixes.
