- Revert some earlier changes to CAS in an effort to reduce noise.

- Added option for mesh edge detection to Kuwahara (kuwaharaPreserveEdges) to reduce colour bleeding and improve definition of objects. Can be disabled by setting the value to 0.

- Slight modification to outlines to improve the appearance of distant outlines.

- Added additional Kuwahara mode (4 - default): samples in all directions, but averaged horizontally to reduce square patterns.

- Added a blend option to control how much of the effect is introduced and how much of the original image is preserved.

- Added a global "effectClipDistance" that determines when effects are generated based on a percentage of the "View Distance" setting.

- Minor adjustment to DepthBlur.

- Improved DepthBlur

- Added different sampling modes to Kuwahara.

- Mode 1 (default): samples in two opposing diagonals to reduce "square" patterns and halves GPU time, improving performance.

- Mode 2: samples in three directions - improving performance over mode 3.

- Mode 3 (original): uses the full Kuwahara omni-directional sample - worst performance and can lead to "square" patterns.

- Kuwahara added back as an optional filter.

- Repurposed Kuwahara to act as a depth based blur effect.
- Modified CAS resulting in increased clarity.

Appologies in advance if this modifies anyone's custom settings.
Responding to feedback the following alterations were made.

- Outlines will now fade over distance by default.
- Colourful default has been reduced to avoid over saturation.
- Posterise default has been reduced to avoid over saturation.
If you perfered any of the old default values, they can be changed back in ./materials/common/NativeStylise.program

It would still be ideal to have these settings attached to sliders, but at present it does not seem possible.
