defined by a distance function
Material needs to output distance to an object through OpacityMask, given the LightVector
position.
* can be quite slow (needs to evaluate the distance function for many steps) when large on screen
* normal is reconstructed from the distance function (6 extra evaluations)
* intersects with the scene like any other z buffer object
* Distortions are possible but require more steps ()
* can be animated but motionblur and TemporalAA will be problematic
* shadow receiving, lighting, sorting all works like any opaque
* can output any GBuffer attribute and use any existing shading model
not done yet:
* shadow casting
* quality settings (step count, hit threshold)
* material normal/bump adjustment
* optimizations
maybe later:
* transluceny volumetric e.g. clouds
* create material functions for the usual primitives and operations

Slate - IT'S FIXED! No more clip rounding error in Slate causing the last column or row of pixels to sometimes get clipped incorrectly. In slate we do pixel snapping on each vertex individually, which means that a box that's at x.3 and extends to w.7, will visually rendered at x to (w+1). The clipping rect was determined in pre-vertex rounding space, the clip rect is represented as origin, extentsX and extentsY. The extents are all computed in pre-pixel snapping space, so a box that goes from x.3 to w.7, becomes an extents of z.4, and is then rounded down. Meaning that on certain pixel offsets, some boxes ended up with an extents that is 1 pixel smaller from the visual version where each vertex is rounded individually. The solution is to perform pixel snapping on the axis aligned clipping rect, which is then used to create the rotated clip rect which is formed with the extents, then to transform it, and again pixel snap.
...
Also removing the option to use halfs for clipping data when sending it to the pixel shader as it doesn't make a ton of sense to keep this codepath available after discussing it with the others working on Slate.

Slate - Disabling the float16 precision version of the slate shader on all platforms. Since the clip values are all in window space, it's terribly easy on modern monitors to exceed single digit precision (2048), causing multiple columns worth of additional pixel clipping erroneously. Tweaking the way we pass that down to the vertex shader for compile so that it now properly algins with whatever we set the option to in C++. We can consider turning it on for platforms where it wont matter, like the consoles 1920 will be your largest visible value.
