[Bf-taskforce25] Game Settings - rna questions, discussion and UI.

[Dalai Felinto]

So this is the summary of the discussion I had with William:

* Game Data will be stored in Scene->GameData and
Scene->Object->ObjectGameSettings.
 - ObjectGameSettings is already completely wrapped. Now we need to
wrap dynamic material properties to Material RNA (although they will
be accessed from buttons_window (scene->ob)).

Regarding UI:
* Game Menu: let's keep the same options as before without GLSL options

* Object->ObjectGameSettings: in buttons_window
  - move physic properties from logic_space to buttons_window
  - that will include an ID material for setting material dynamic
physic properties (enabled for editing when noFH=TRUE)

* Scene->GameSettings: in logic_space for the time been.
  - World: bring world data here (bullet on/off, gravity, fps, log, ...)
  - GamePlayer: (ie framing and size)
  - No Stereo / Stereo / Dome (remove dome and no_stereo from stereo type list)

Since some of those changes will require DNA changes, that will imply
in some do_version() as well. Some of them (eg player settings) we can
remove and set, set a default and let the user re-assign it.

>From Ton: "we need to figure out what need to be
re-addressed/deprecated and what is not a big deal to be re set by the
user"

Well, I'm planning to continue tackling it next week (Wednesday or
Thursday). So if anyone has any other suggestions to that, please do
it before that date. In the mean time if anyone wants to work on the
Game Menu, please help yourself :) That's not necessarily related with
the other changes I'm planning to do.

Cheers,
Dalai
