egl: Introduce meta_egl_create_dmabuf_image This bit of code was more or less duplicated in meta-renderer-native-gles3.c and meta-wayland-dma-buf.c. Start consolidating the two implementations by moving the *-gles3.c function into meta-egl.c and generalizing it so it could also accommodate the meta-wayland-dma-buf.c usage. The workaround in the *-gles3.c implementation is moved to the caller. It is the caller's responsibility to check for the existence of the appropriate EGL extensions. Commit 6f59e4858e24c828e3ab0e611d36dfaaded1b272 worked around the lack of EGL_EXT_image_dma_buf_import_modifiers with the assumption that if the modifier is linear, there is no need to pass it into EGL. The problem is that not passing a modifier explicitly to EGL invokes implementation-defined behaviour, so we should not have that workaround in meta-egl.c. This patch intends to be pure refactoring, no behavioral changes. The one change is the addition of g_assert to catch overwriting arbitrary memory. https://gitlab.gnome.org/GNOME/mutter/merge_requests/615
