The gir generator wrongly assume that the vfunc GstGLFilterClass.filter() and the method gst_gl_filter_filter_texture() are related. As a result it complains about not matching argument names. Workaround this by naming both of their arguments input and output. Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-plugins-base/-/merge_requests/664>
