Handling resize when SDL_WINDOWID is set

I noticed that among other things, SDL (1.2.x) does not handle
resize requests when an externally supplied SDL_WINDOWID
is used.

This is probably a good default, but the problem is that
there is no way to override this feature short of
adding extra code to the application, so that it calls
itself the equivalent of X11_ResizeWindow().

Any chance that in future versions of the library
this behaviour (supporting resize with
externally-supplied windows) can be made configurable
at runtime just using some environment variable ?

As i said in another thread


i am writing some code to embed generic SDL apps within firefox
plugins, and having the application behave so differently
depending on who creates the window is slightly annoying…
