Currently, grease pencil conflicts with such operators
as undo and set object mode which makes behavior totally
unpredictable and crash for some cases.
The only way to solve this proper is to ger rid of pointers
to data which can chage stored in operator custom data.
if vec.dot(vec) > some_distance*some_distance:
do_something()
might not be quite as obvious looking as:
if vec.length_squared > some_distance*some_distance:
do_something()
As to why you'd want to use length_squared over length is that length uses a square root, which isn't always necessary for simple distance checks (e.g., closest object, checks like the ones above, ect).

Lack of normal normalisation caused scaling issues. SIGGRAPH fix by jahka and jesterKing. Thanks to host dfelinto with entertainment provided by slikdigit.
2 changes
- When writing OGG only allow Theora encoding, this fixes the crash.
- When setting the MPEG preset, dont allow the 'Codec' to be left as Theora, this is just confusing.
* note that this is highly confusing for users and devs - there are 4 places to set the codec/format, with both python and C presets :S.
added _prop suffix to ui functions which take a prop rather then a propname, may change this later since its not that nice but for gsoc branches this keeps existing UI functions working the same.
Diff Keymaps
User edited keymaps now no longer override the builtin keymaps entirely, but
rather save only the difference and reapply those changes. This means they can
stay better in sync when the builtin keymaps change. The diff/patch algorithm
is not perfect, but better for the common case where only a few items are changed
rather than entire keymaps The main weakness is that if a builtin keymap item
changes, user modification of that item may need to be redone in some cases.
Keymap Editor
The most noticeable change here is that there is no longer an "Edit" button for
keymaps, all are editable immediately, but a "Restore" buttons shows for keymaps
and items that have been edited. Shortcuts for addons can also be edited in the
keymap editor.
Addons
Addons now should only modify the new addon keyconfiguration, the keymap items
there will be added to the builtin ones for handling events, and not get lost
when starting new files. Example code of register/unregister:
km = wm.keyconfigs.addon.keymaps.new("3D View", space_type="VIEW_3D")
km.keymap_items.new('my.operator', 'ESC', 'PRESS')
km = wm.keyconfigs.addon.keymaps["3D View"]
km.keymap_items.remove(km.keymap_items["my.operator"])
Compatibility
The changes made are not forward compatible, i.e. if you save user preferences
with newer versions, older versions will not have key configuration changes that
were made.
- icons were scaling by the sqrt(dpi)/8.48528, but infact they only need to be scaled by (dpi/72).
- UI_icon_get_width value was being used without multiplying by dpi scale.
dont show a popup anymore, was silly because you had to change the value for before anything was done, can use f6 redo popup instead, sequencer should eventually have a view3d operator redo panel.
