No special bind/unbind needed for standalone viewer, so can just use a
static stub in the display callback.

To make a generic OSL shader connectable to other nodes, the parameters
must be declared via "input" and "output" child elements:
<osl_shader name="tex" src="./osl/stripes.osl">
<input name="Stripes" type="int" />
<output name="ColorOut" type="color" />
</osl_shader>
`name` must be the same as the OSL shader parameter name.
`type` must be one of float, int, color, vector, point, normal, closure,
string (matching cycles socket types)
Beyond this the OSL script nodes then work just like all other nodes.
OSL parameter sockets can be connected to other cycles nodes:
<connect from="checker color" to="tex Stripes" />
<connect from="tex ColorOut" to="floor_closure color" />
They can set default values for the input sockets by attributes of the
main node element:
<osl_shader name="tex" src="./osl/stripes.osl" Stripes="3" >
<input name="Stripes" type="int" />
<output name="ColorOut" type="color" />
</osl_shader>
This system of specifying custom attributes should probably be changed,
since it can easily create name conflicts and arbitrarily long elements.
But that is a different issue to be solved for all nodes in general.
Indirect and Direct samples can now be clamped individually. This way we can clamp the indirect samples (fireflies), while keeping the direct highlights.

WARNING: This breaks backwards compatibility. If you had Clamping enabled in an old file, you must re-enable either Direct/Indirect clamping or both again.

* Very simple implementation, only allows for 1 output socket. As we haven't decided yet whether we keep the XML API, rather not spend more time on this now.
* To use an external osl shader, put the .osl file next to the xml file.
* Parameters: "output" is the output socket name, "output_type" the variable type (float, color and closure color are supported).
Example:
<osl_shader name="tex" src="ramp_closure.osl" output="Phong" output_type="closure color" />
<connect from="tex Phong" to="output surface" />
* Change Info in header, put more important info to the left
* API: Move Camera width/height to camera, add some film properties
* Add ESC key to help menu
This is very basic for now, but can be extended with more info (available devices for example) later.
Thanks to Bastien and Sergey for some help with the glRect coordinates stuff.
* Henyey-Greenstein scattering closure implementation.
* Rename transparent to absorption node and isotropic to scatter node.
* Volume density is folded into the closure weights.
* OSL support for volume closures and nodes.
* This commit has no user visible changes, there is no volume render code yet.
This is work by "storm", Stuart Broadfoot, Thomas Dinges and myself.
This actually works somewhat now, although viewport rendering is broken and any
kind of network error or connection failure will kill Blender.
* Experimental WITH_CYCLES_NETWORK cmake option
* Networked Device is shown as an option next to CPU and GPU Compute
* Various updates to work with the latest Cycles code
* Locks and thread safety for RPC calls and tiles
* Refactored pointer mapping code
* Fix error in CPU brand string retrieval code
This includes work by Doug Gale, Martijn Berger and Brecht Van Lommel.

It was never fully implemented and will be replaced by OpenSubdiv. Only linear
subdivision remains now. Also includes some refactoring in the split/dice code,
adding a SubdParams struct to pass around parameters more easily.
* More build fixes, 2 link errors remain. http://www.pasteall.org/45279
Note: Probably those paths should only be added for Windows and Linux, as "OPENIMAGEIO_LIBPATH" already inherit them for Mac OS. Also "OPENIMAGEIO_LIBRARIES" inherits the libs for Linux already. Is that intended or a lack of consistency?
* Fix some link errors on Windows, still missing png, zlib, jpeg and tiff.
I couldn't yet figure out the correct flags to pass on here, and the 2300 lines huge main CMakeLists file doesn't help with it...
