minor speedup for UI draw code, noticed ui_get_but_val() could be called 3-5 times per button draw,
for RNA buttons this gets the entire array for each call so its not great to call many times.

Merged changes in the trunk up to revision 37539.

Conflicts resolved:
source/blender/render/intern/source/pipeline.c

Also fixed an inconsistent conflict resolution in the last commit with
regard to release/scripts/startup/bl_ui/properties_render.py. This
problem resulted in empty menus in the GUI.

include some extra search paths for cmake openexr

fix to FindOpenEXR pointed out by Sergey Sharybin,
also added check for IlmThread and marked individual library cache variables as advanced.

== Simple Title Cards for Sequencer ==

This commit adds an experimental effect strip to the sequencer: "Title
Card".

This is useful for adding simple one-line text section headers or
"title cards" (i.e. title + author/contact details) to video clips,
which is often seen in demo videos accompanying papers and/or
animation tests.

See http://aligorith.blogspot.com/2011/06/gsoc11-simple-title-
cards.html for some more details on usage.

Code notes:
- There are a few things I've done here which will probably need
cleaning up. For instance, the hacks to get threadsafe fonts for
rendering, and also the way I've tried to piggyback the backdrop
drawing on top of the Solid Colour strips (this method was used to
keep changes here minimal, but is quite fragile if things change).

BGE_Animations: Removing the Fcurve Actuator as a possible actuator type, but keeping a lot of the code around as reference.

BGE Animations: Making sure the Action Actuator has a valid action before attempting to play.

BGE Animations: FCurve Actuators are now converted to Action Actuators in do_versions(). Note: The fcurve actuator still needs to be removed from menus and such.

BGE Animations: Adding the ipo flag options to the action actuator. This still needs more testing.

Blenderplayer: Setting G.main to NULL after it's freed to avoid issues later with GPU_free_images()

cleaned up event logging, added HID -> function table for SpacePilot PRO

fixed typos, renamed the HID -> function lookup tables

mapping HID button codes -> functions, for SpaceNavigator and SpaceExplorer

Committing patch #25676 Anisotropic filtering in viewport and BGE by me.

This patch adds anisotropic filtering of textures in the viewport and the BGE. The quality of the filtering is adjustable in the user preferences under System. For more information on anisotropic filtering:
http://en.wikipedia.org/wiki/Anisotropic_filtering

One current limitation of this setup (having the option a user preference) is it makes runtimes more troublesome. Runtimes don't have user preferences set, so for now the blender player defaults to 2x AF. Options will be added later to change this value (probably a command line option).

3D Audio GSoC:
Temporary fix for MSVC.

Camera tracking integration
===========================

- Marker's preview panel is now avaliable with any
tool selected (except NONE).
- Fixed bug with marker's point going outside of pattern
when scaling pattern which isn't centered to marker's pos.
- Changed a bit pattern area image generation.
Now it shouldn't give artifacts with different kinds of
offsets caused because of float-?int conversions.
- Rollback code for generating flat buffer of search area
when tracking. It'll be more accurate with current position
calculation.
Will switch to BKE_tracking_acquire_search_imbuf when
backwards position calculation would be implemented.
- Added option to make markers thin. It's in Debug panel due
to this option was really useful for debugging preview image
but not sure it'll be useful for artists.
- Added "View Selected" operator (hotkey is numpad period).
Fits view to show all selection at the frame.
- Added option "Lock to Selection" which locks view
to show centered selection. Useful to visual markers
tracking during playback.
This option is on "Display" panel.
