- It's like sketch mode for lines, but you're specifying line knots
by clicking on position you want to add next knot.
- View can be navigated between knots creation.
- Holding LMB down and sliding mouse will lead to new segment preview
so it can be created more accurate.
Additional change: fixed GP->Bezier conversion. Last point used to
be ignored in this operator.

- Implement own undo stack for grease pencil, so now there'll be no keymaps conflicts.
- Supported redo's during sketch session.
- Get rid of flag stored in Globals -- use undo stack to check if grease pencil session is active.

Causing a flurry of refresh file prompts post-commit,
Confusing local diffs and causing merge conflicts,
Stating the obvious; redundant and useless...

* Convert operator - can currently be used to convert active Grease Pencil layer to curves. I had a look at making this part of a special "curve sketching" macro, though it seems that we cannot have modal operators coming first in a macro (and also cannot specify operator calling modes)
* Delete Active Frame operator - does what its name say it does. It deletes the active frame for the active layer of Grease Pencil sketches.

* Smooth strokes can now be drawn again, with normal (i.e. reasonably speedy feedback again).
Previously slow drawing was caused by a bad notifier being used - the full screen was redrawn each time instead of just the relevant region. Now, only the relevant region is redrawn while drawing, and a proper flush is done for the rest of the screen at the end.
* Made drawing straight lines a proper drawing 'mode' for Grease Pencil now. Use the Ctrl-D-LMB hotkey to draw straight lines in this way. The (buffer) line drawn now will accurately represent the final straight line instead of drawing the freehand path taken as before.

Restored the UI for access to the GP layers.
There are still a few minor bugs here:
* Wrong icons on the toggles - even when they're enabled, they only show a single state
* The ID-template doesn't seem to be showing up. Dunno what's going wrong there...

This commit is the start of the new Grease Pencil implementation. I've just ported the old code to make it work with operators, and to store its data in Grease-Pencil datablocks.
However, this is currently still really buggy, with only the barebones of the drawing/creation tools restored (no UI panels, no options). To use (not recommended), use D+S+move_mouse (and click when finished) for now. There are some rather serious event handling errors going on here...

Patch from Joshua, converting Grease Pencil to 2.5.
All GP data now is an ID block, allowing re-use, link and append.
For better contextual control within 2.5, these GP ID's will get
linked to actual data, like NodeTrees, Scenes, Images or Objects.
That will ensure Undo works, and opens up exciting new use cases
as well. :)
Patch note: on reading files, GPencils linked from editors will
get moved to the main library, using standard naming (indicating
where it was used), and with "Fake User" set. That way the user
can manually relink the pencils where appropriate.
We can check on just linking GP to some default, like 3d window
pencils to Scene? Nice to experiment with.
Notes for Joshua:
- for reading old GPencil, it has to use old code as well, meaning
to tread data as "indirect data, within another ID".
- Saving ID data means the chunk in file BHead needs the ID_GD code,
and not "DATA", which indicates 'indirect data'. That's the file
format spec.
- I've added do_versions_gpencil_2_50(), feel free to further tweak
things here, like linking things to scene or so.
- Formerly GPencil saved 2.50 files won't convert gpencil

GPencil code back!
Joshua will probably take this further. I've added XXX notes
where fixes are required. Also note that ED_gpencil.h has
all old exports, which is probably not needed, most can go
to gpencil_intern.h
Also added Makefile fixes for sculpt
