Checks if context is valid or reallocs a new one instead.

If context is NULL, just calls sws_getContext() to get a new one. Otherwise, checks if the parameters are the same already saved in context. If that is the case, returns the current context. Otherwise, frees context and gets a new one.

Be warned that srcFilter, dstFilter are not checked, they are asumed to remain valid.
