12k lines of sequencer back! Only seqaudio.c skipped for now.
Notes:
- it only draws now, nothing refreshes or edits.
- fixed bug in view2d.c with vertical grid step being 0.0f
- render code and fileselect code is #ifdeffed out
- sequence evaluation code moved to blenkernel, so it can
be used for render without bad level calls
General note; sequencer code is very untidy, mixing styles too
much. Tried to clean it some, but it would be nice if formatting
is kept consistant from now on.
that is not supposed to be in the editor but at blenkernel level
to avoid bad level calls. Added sequencer free and strip iterator
functions there and used them to make sequencer data load/save
work again.
