use strict flags for kdopbvh, also assert when invalid treetype is passed, rather then failing silently.

Code cleanup / Cycles:
* Removed unused member of the device_memory template.

Code cleanup / Cycles:
* Avoid special code, when Subsurface is enabled.
Ideally we should only use the function, and get rid of the extra duplicate, but this is slower on CUDA.

Compile fix / Cycles:
* 'T' is now also used for the Subsurface closure.

Add new cursor types to data handling to account for Intuos 4 device (pen and eraser).

Thanks to Ayden Polat for helping to find out the cursor type codes.

fix for building on msvc

better fix for r59794, register a gesture when the mouse goes outside the actionzone.

fix for window join action being interpreted as a split.

The limit for dragging a gesture on an area corner was smaller then the area hot-spot,
so you could click on the right-most side of the bottom-left corner, drag left - pass the gesture threshold and still be in the same area. so a motion intended as a join would register as a split.
Happened more with high DPI values. fix by ensuring the drag limit is always higher then the hotspot.

fix for glitch splitting horizontally with a high dpi, could make areas smaller then the header which pushed the original view out of the screen.

style cleanup

tweaks to fly mode
- rotating the view is faster.
- arrow keys work (was only wasd-rf before)
- when stationary wheel or +/- will set z direction (so mouse wheel always sets the fly axis back to z)

debug option for modifier stack calculation USE_MODIFIER_VALIDATE,
checks that every modifier gives a valid mesh (very slow) - so off by default even in debug mode.

Added better support for line styles in the Outliner.

Fix cycles CUDA/OpenCL build error after recent change.

Fix for redundant multiple animation data items of the same line style in DopeSheet.
This could happen when a line style is shared by multiple linesets within a scene.

Fix for missing filter button to visualize/hide animation data related to line styles.

Fix #36649: Drivers for Freestyle parameters in Render Layer panel don't appear in Graph Editor.

The channels define code in ANIM_init_channel_typeinfo_data() was not synchronized with the
definition of channel types (eAnim_ChannelType) in ED_anim_api.h.

Fix a few issues reported by coverity scan.

Cycles: add a sharpness input to the Cubic SSS falloff. When set to 1 this will
give a result more similar to the Compatible falloff option. The scale is x2
though to keep the perceived scatter radius roughly the same while changing the
sharpness. Difference with compatible will be mainly on non-flat geometry.

replace sqrt(dot()) with length functions.
