Support for EXT_image_dma_buf_import_modifiers doesn't necessarily indicate support for modifiers. For instance, Mesa will advertise EXT_image_dma_buf_import_modifiers for all drivers. This is a trick to allow EGL clients to enumerate supported formats (something EXT_image_dma_buf_import is missing). For more information, see [1]. Add a new wlr_egl.has_modifiers flag which indicates whether modifiers are supported. It's set to true if any eglQueryDmaBufModifiersEXT query returned a non-empty list. Use that flag to figure out whether the buffer modifier should be passed to the EGL implementation on import. [1]: https://github.com/KhronosGroup/EGL-Registry/issues/142
