Hi,
I updated the inclusion mechanism a bit. It's now:
% initializations:
%
% - pass settings from tex to mp (delayed expansion)
% - used by context core (and modules)
% - cummulative definitions
% - flushed each graphic
% - can be disabled per instance
% - managed at the tex end
%
% extensions:
%
% - add mp functionality (immediate expansion)
% - cummulative
% - all instances or subset of instances
% - can be disabled per instance
% - managed at the lua/mp end
% - could be managed at the tex end but no real reason and also messy
%
% definitions:
%
% - add mp functionality (delayed expansion)
% - cummulative
% - per instance
% - managed at the tex end
%
% inclusions:
%
% - add mp functionality (delayed expansion)
% - cummulative only when [+]
% - per instance
% - managed at the tex end
%
% order of execution:
%
% definitions
% extensions
% inclusions
% beginfig
% initializations
% graphic
% endfig
So, the main differences are:
(1) inclusions bound to default or specific instanced
(2) extensions more flexible
