Hi All,

This is a cast from a pointer to 32-bit integer, which is 64-bit unsafe. I've added an m_pattern member to replace m_texture_id.

I've added a configure option --enable-renderer=[renderer], where renderer is either opengl or cairo (the default is still opengl).

This work increases the importance of a cleanup of gnash.cpp (which is already underway in the form of a frontend library) - when the cairo backend is enabled, currently two windows are created. Fixing that is nontrivial due to the goop in gnash.cpp.

I got Gnash mostly compiling on OS/2 - however the Cairo backend depends on cairo-xlib.h which isn't available on OS/2 as OS/2 doesn't use X.

Is there a more platform independent way of implementing a Cairo backend?
