(1) metafun is a format and will be loaded first
(2) inclusion scome after loading the format
(3) context only sets a bunch of variables which tell metafun certain 
things

i'm not sure what you mean with tinkering

what parameters give you problems?

concerning backgrounds  and plain.mf ... metafont has bacckgrounds, 
metapost doesn't ; in mp the background is used for unfilling

if you want to set the background / add own stuff you can probably best 
append the relevant settings / definitions to the extra_beginfig string 
(grep for that one)
