Comment 10 for bug 825957

Awesome! I especially love the GCC macro which reads beautiful in the code. I merged this as is, only adding a TODO for me to check if Rect::contains can be used in rt_render - very likely I only missed this when I wrote the code.

Compile time warnings are very tricky of course - other systems might still give some for the very same compiler, so I am not sure what to do with this bug now. I feel your work warrants a closed bug though, so I just go ahead and close it :P.
