- move static declarations and data definitions out of headers. the BGL module still need cleaning. - move declarations out of modules.h and into appropriate .h files. modules.h still exists as a container for the few modules that need to #include almost everything. - all files now have a $Id tag and have been formatted by indent there are no changes to executable code. pre-commit versions are tagged with bpy-cleanup-pre-20041007 for the sake of paranoia.
