* - Added support for hair for ray tracing effects (#6327)

* Avoid negative input to sqrt() (#6397)

- The calculation of `k` is not numerically robust when done in FP16 and might generate a negative value.
- This can be observed as rendering artifacts on Mali drivers newer than Bifrost/Valhall R21.
- This commit fixes this by by clamping `k` to [0, inf] before the `sqrt()`.
- On Mali-G77 the clamp compiles down to a free output modifier on the previous instruction, so there's no performance impact.

    Use 2-component edge texture for SMAA on Mali (#6066) (#6196)

    The SMAA edge texture only requires 2 components, but using 4 may be
    faster on some vendors (SMAA authors mention it is faster on Nvidia).
    2 components is faster on Mali, so make sure 2 components is used
    when running on a Mali device but keep 4 components for other vendors.

    Measurements were done in the URP default template scene with SMAA on
    medium settings and all other post-processing effects turned off on a
    Mali G-76.

    Mali Core Internal Bus Write Beats: Tile buffer internal -12.6% (+-2.3%)
    Mali Core Tiles (CRC): Killed tiles: +16.1% (+-2.3%)
    Mali External Bus Accesses: Write transaction: -10.9% (+-2.3%)
    Mali External Bus Beats: Write beat: -10.8% (+-2.3%)
    Mali External Bus Outstanding Writes: 0-25%: -14.8% (+-2.1%)
    Mali L2 Cache Lookups: Write lookup -10.2% (+-3.2%)

    * Delay discard of fragments during decal projection (#5283)

    * Delay discard of fragments during decal projection

    Metal Shading Language declares that fragment discard invalidates
    derivatives for the rest of the quad, so we need to reorder when
    we discard during decal projection, or we get artifacts along the
    edges of the projection (any partial quads get bad partial derivatives
    regardless of whether they are computed implicitly or explicitly).
