* Change default blur type (Blur Node) to Gaussian. Feature Request by Sebastian König.
Patch by Troy Sobotka, approved by Campbell, Sergey and myself.

the parent material also had alpha enabled. However it's useful to have it do
this even if the main material does not need alpha, to mix textures.

It would actually show after save and reload, the subtype and min/max were
not properly initialized for node output sockets.

* MEM_CacheLimitier - Size type to int conversion, should be safe for now (doing my best Bill Gates 640k impression)
* OpenNL CMakeLists.txt - MSVC and GCC have slightly different ways to remove definitions (DEBUG) without the compiler complaining
* BLI_math inlines - The include guard name and inline option macro name should be different. Suppressed warning about not exporting any symbols from inline math library
* BLI string / utf8 - Fixed some inconsistencies between declarations and definitions
* nodes - node_composite_util is apparently not used unless you enable the legacy compositor, so it should not be compiled in that case.
Leaving out changes to BLI_fileops for now, need to do more testing.

This commit makes BKE_image_acquire_ibuf referencing result, which means once
some area requested for image buffer, it'll be guaranteed this buffer wouldn't
be freed by image signal.
To de-reference buffer BKE_image_release_ibuf should now always be used.
To make referencing working correct we can not rely on result of
image_get_ibuf_threadsafe called outside from thread lock. This is so because
we need to guarantee getting image buffer from list of loaded buffers and it's
referencing happens atomic. Without lock here it is possible that between call
of image_get_ibuf_threadsafe and referencing the buffer IMA_SIGNAL_FREE would
be called. Image signal handling too is blocking now to prevent such a
situation.
Threads are locking by spinlock, which are faster than mutexes. There were some
slowdown reports in the past about render slowdown when using OSX on Xeon CPU.
It shouldn't happen with spin locks, but more tests on different hardware would
be really welcome. So far can not see speed regressions on own computers.
This commit also removes BKE_image_get_ibuf, because it was not so intuitive
when get_ibuf and acquire_ibuf should be used.
Thanks to Ton and Brecht for discussion/review :)

this node allows for more control for normalization of the mapped input range.
Made during BlenderPRO 2012 - Brasilia, Brazil :)
Idea and testing: Daniel Salazar
Implementation: yours truly

This is probably versioning issue happened when both trunk and tomato
were mixed to work on the same file.
Anyway, there're few files here locally and it's probably other users
do have the same files, so lets keep things safe here :)

for now subtype is not defined, but once we start parsing the metadata we can set texture inputs as FILEPATH
also, it takes relative strings and convert to absolute for all strings (which is arguably a good solution, but
should work for now)

* Tangent: generate a tangent direction for anisotropic shading. Can be either
radial around X/Y/Z axis, or from a UV map. The default tangent for the
anisotropic BSDF and geometry node is now always radial Z, for UV tangent use
this node now.
http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/Nodes/More#Tangent
* Normal Map: generate a perturbed normal from an RGB normal map image. This
is usually chained with an Image Texture node in the color input, to specify
the normal map image. For tangent space normal maps, the UV coordinates for
the image must match, and the image texture should be set to Non-Color mode
to give correct results.
http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/Nodes/More#Normal_Map
* Refraction BSDF: for best results this node should be considered as a building
block and not be used on its own, but rather mixed with a glossy node using a
fresnel type factor. Otherwise it will give quite dark results at the edges for
glossy refraction.
http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/Nodes/Shaders#Refraction
* Ambient Occlusion: controls the amount of AO a surface receives, rather than
having just a global factor in the world. Note that this outputs a shader and
not a color, that's for another time.

* Fix GLSL memory leak in the (vector) math node.

A test variable needed to be absoluted (positive).
Gives expected resuts on negative raiser values.

(In old compo code too, not effective).

Shader nodes (Blender Internal), Math node Power() didn't accept negative
values for input. Added same code as for compositor case - only allow to
raise with integer values for negatives.

* Shader script node added, which stores either a link to a text datablock or
file on disk, and has functions to add and remove sockets.
* Callback RenderEngine.update_script_node(self, node) added for render engines
to compile the shader and update the node with new sockets.
Thanks to Thomas, Lukas and Dalai for the implementation.

generated as a transient list that is returned from the callback and had to be freed by the caller. These internal links are used for muted nodes, disconnect operators and reroute nodes, to effectively replace the node with direct input-to-output links.
Storing this list in the node has the advantage of requiring far fewer calls to the potentially expensive internal_connect callback. This was called on every node redraw ...
Also it will allow Cycles to properly use the internal links for muted nodes, which ensures consistent behavior. The previous method was not applicable in Cycles because transient list return values are not supported well in the RNA and particularly the C++ API implementation.

not do correct partial updates, now it remembers if the opengl texture is a
non-color data texture or not and takes that into account for the update.
Also includes some renaming ncd => is_data for consistency with color space
terminology used elsewhere.

Problem here is that muted nodes and reroute nodes are supposed to be removed from the execution node tree during the localize function. However, this is function is apparently only used during preview renders and must be considered a hack (is there anything that is not a hack in BI?)
Now the mute/reroute check happens in the node tree exec functions still used by BI and the legacy compositor and texture nodes. It uses the same internal_connect function from nodes to assign input stack indices directly to outputs (which also avoids overhead). Localize function also still does this. Cycles/Tile should also implement muting/reroute in their intermediate node layers by using this function, then it could be removed from localize too.

nodes. This was a feature i tested a while back but was only partially supported by Blender Internal renderer and the old compositor. The main idea was to have nodes that automatically mirror input and output sockets to support incremental changes of "internal variables".
It is not a well-supported feature of the primary node systems (shader, compositor, texture) in Blender. If anybody wants to create a node system that has actual use for loops, they can do so much more elegantly with Python nodes, but it does not have to be a core node type in Blender. Removing this should ease node code maintenance a bit.

This makes it possible to create pixelized scale in the Tile compositor.
Just append the node in front of a scale node or where you want the pixelization to take place.
There were some bugs on this subject, but they used the work around to add a blur size of 0 in the place where they need the pixelization.

Solved by insuring image buffer is loaded before checking for whether color

- move object_iterators.c --> view3d_iterators. (ED_object.h had to include ED_view3d.h which isn't so nice)
- move projection functions from view3d_view.c --> view3d_project.c (view3d_view was becoming a mishmash of utility functions and operators).
- some some cmake includes as system-includes.
