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.
