[Gnash-dev] Simple tasks for OpenGL and Cairo to allow automated testing

[strk]

Before the 0.8.0 release I think we should have 'make check'
effective with all renderers. For OpenGL  and Cairo this means
implementing a couple of interfaces of gnash::render_handler class:

        virtual bool getPixel(rgba& color_return, int x, int y);

and

        virtual unsigned int getBitsPerPixel() const

Both are used for pixel checking by a few test runners.
See dox in render_handler.h for more info.
