Used together with the X Composite extension, * it allows to display the content of X Windows inside Clutter. * * The class requires the GLX_EXT_texture_from_pixmap OpenGL extension * (http://people.freedesktop.org/~davidr/GLX_EXT_texture_from_pixmap.txt) * * The GL_ARB_texture_non_power_of_two extension will be used if it is * available. Otherwise it will try to use the * GL_ARB_texture_rectangle extension. If both are available you can * force it to prefer the rectangle extension by setting the * CLUTTER_PIXMAP_TEXTURE_RECTANGLE to 'force'. To prevent it ever * using the rectangle extension you can set it to 'disable'. */ #ifdef HAVE_CONFIG_H #include "config.h" #endif #include #include "../x11/clutter-x11-texture-pixmap.h" #include "clutter-glx-texture-pixmap.h" #include "clutter-glx.h" #include "clutter-backend-glx.h" #include "../clutter-util.h" #include "../clutter-debug.h" #include "cogl/cogl.h" typedef void (*BindTexImage) (Display *display, GLXDrawable drawable, int buffer, int *attribList);
