This inconsistency drove me totally crazy, it's really confusing
when it's inconsistent especially when you work on both Cycles and
Blender sides.
Shouldn;t cause merge PITA, it's whitespace changes only, Git should
be able to merge it nicely.
Thanks for Aldo Zang for the help with the fix for the panorama/fisheye
depth of field calculation and the overall math.

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
* 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.
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.
Regular rendering now works tiled, and supports save buffers to save memory
during render and cache render results.

the implementation was following my early commit for Math node
I haven't had a chance to run those through Brecht, but would like to do eventually. (they work fine though)
