This has the following visible changes: - GBM is required only for OpenGL dma-buf. - X11 is explicitly required by gtk-egl. - EGL is now mandatory for the OpenGL displays. The last one needs some detailed description. Before this change, EGL was tested only for OpenGL dma-buf with the check of EGL_MESA_image_dma_buf_export. However, all of the OpenGL displays depend on EGL and EGL_MESA_image_dma_buf_export is always defined by epoxy's EGL interface. Therefore, it makes more sense to always check the presence of EGL and say the OpenGL displays are available along with OpenGL dma-buf if it is present.
