30bffb5a3a Nodes: add sqrt, ceil, floor and fract to math nodes. 
This works for Cycles, Eevee, texture nodes and compositing. It helps to
reduce the number of math nodes required in various node setups.

6862762685 Cycles/Compositor: Add arctan2 operation to the Math node 
The Math node currently has the normal atan() function, but for
actual angles this is fairly useless without additional nodes to handle the signs.

Since the node has two inputs anyways, it only makes sense to add an arctan2 option.

ee36e75b85 Cleanup: Fix Cycles Apache header. 
This was already mixed a bit, but the dot belongs there.

89fc09b3be Fix for OSL bug reported on IRC by Pablo Vasquez: Clamp option of the math node in OSL produces bad results. Really stupid bug, OSL math node was assigning the clamped 1st input value instead of the 
clamped result of the actual operation.

615fe0295f Cycles OSL: refactoring and fixes 
* Moved kernel/osl/nodes to kernel/shaders
* Renamed standard attributes to use geom:, particle:, object: prefixes
* Update stdosl.h to properly reflect the closures we support
