Waffle is a cross-platform C library that allows one to defer selection of an OpenGL API and window system until runtime. For example, on Linux, Waffle enables an application to select X11/EGL with an OpenGL 3.3 core profile, Wayland with OpenGL ES2, and other window system / API combinations. Waffle's immediate goal is to enable Piglit, Mesa's OpenGL test suite, to test multiple OpenGL flavors in a cross-platform way. However, Waffle's design does not preclude it from being useful to other projects.
