Under the following situation, visual_drawable_type function (defined in src/xdemos/glxinfo.c and called from glxinfo -v) returns wrong type text.
1. a visual calls visual_drawable_type(GLX_WINDOW_BIT);
2. then, another visual calls visual_drawable_type(GLX_PIXMAP_BIT);

In the later case, it expects to return "pixmap". But actually it returns "window,pixmap,". The reason of this behavior is that the function advances a pointer without testing a flag, and it doesn't clear previous texts.

I found this bug when I was testing Oracle VirtualBox's feature on Ubuntu 10.10.
I made a patch, so attach it.
