[ #4143 ] Methods for reading bone movement limits
Submitted By:
Aron Cristian (criller)
Gives the ability to return/set the limitations on a posebone when that bone is part of an IK chain.
New Constraint API. Constraints are accessible through a "constraints"
attribute in poses and objects. Would be REALLY NICE for armature users to
pound on this code.
- Found several places, where people explicitly casted the frame number
to short.
- Fixed the crash in BPY_interface by adding an empty line (to make it
recompile everywhere, make clean doesn't help...)
For the build system maintainers:
Problem was: The change in makesdna changed the position of the
scriptlink structure. BPY_interface.c somehow didn't get recompiled
(not even after a make clean!!!) which triggered crashes on adding
scriptlinks.
implicit declarations, redundant redeclarations, missing initializers,
nested externs and other cruft.
Cleaned up includes and moved extern _Type decls from Types.h into
Types.c since that is the only place where they are needed now.
Did not touch Ipo.[ch] since work is on-going there.
