Don't make libgstinterfaces (and thus libgstaudio etc.) indirectly depend on libgstvideo by using the GstVideoRectangle helper structure in the API, which causes undesirable dependencies, esp. with the gobject-introspection (people will point and laugh at us if they find out that libgstaudio depends on libgstvideo). Instead, pass the x, y, width and height parameters directly to the function. Re-fixes #610249.
