* Both paths still exist in code during this transition. The GetDynamicMeshElements path is currently disabled, enable with 'r.UseGetDynamicMeshElements 1'.
* DrawDynamicElements was called once per pass, all sorts of pass-specific cruft had leaked in along with short-term modifications of shared structures (vertex factories and material proxies). DrawDynamicElements was not const, so a bunch of 'update' type work had leaked in. Various PreRenderView implementations relied on the view being in the view family.
* GetDynamicMeshElements is called once in InitViews, and the resulting meshes are used in various passes. GetDynamicMeshElements is const and must not modify the proxy, update work should be pushed to the proxy from the game thread. GetDynamicMeshElements can be called on views that are not in the view family, which allows a proper view for shadow depth passes.
* View mode override functionality moved out of the individual proxies into a centralized place, ApplyViewModeOverrides
* GPU particles not working yet, FRecastRenderingSceneProxy not implemented

- Material editor preview nodes now work when the editor is in es2 mode
- Make editor primitives work in ES2 mode
- Fix slate font rendering in ES2 mode
- Remove ES2 shader de-gamma when in the editor
- Add a new linear sampler type for linear textures
- Various fixes for dynamic feature level switching
- When in an emulated feature level mode, display some text in the level editor viewport saying what feature level we're running
- Removed feature level parameter from USkeletalMesh::GetResourceForRendering. Not used for anything
- ParticleVertexFactoryPool is now creates feature level specific vertex factories.

Last render time for textures can now be exposed via an FLastRenderTimeContainer provided at construction time. Only implemented for texture references. Eventually this can unify last render time for normal textures and texture references.

Moved console variables to their corresponding cpp files where possible.

* Provides mid-range stable AO for dynamic rigid meshes
* Movable sky lights are now supported, and distance field AO is used for shadowing Movable sky lighting from dynamic scenes
* Static meshes are preprocessed into signed distance field volumes at mesh build time when the r.AllowMeshDistanceFieldRepresentations project setting is enabled
* Non-uniform scaling does not work with this method (mirroring is fine), animating through world position offset also causes artifacts as the two representations diverge
* Occlusion is computed along cones to reduce over-shadowing, object distance fields are operated on directly (no hierarchy) to obtain enough resolution to prevent leaking, visibility traces are done with cone stepping to allow better parallelization, and shading is done adaptively in space and time using the surface cache.

There was a bug in setting affinity of a thread that assumed affinity from lookup table with key being a thread name. When names was appended with consecutive numbers (e.g. "RenderingThread 1") the mechanism failed. Refactored this to use special static consts describing affinity override'able by different platforms for different affinity types + possibility of setting affinity per thread.

#summary Rename Trunc, Round, Floor, Ceil to TruncToInt, RoundToInt, FloorToInt, CeilToInt. Added *ToFloat versions. Repeated for FGenericPlatformMath and all derived classes for all platforms wherever applicable. Corrected comment in Fractional and added Frac() which does HLSL-style fractional (x - floor(x)). Checked for compilation on all projects (with cooking levels wherever applicable). Didn't change Fractional to Frac, this will be done in second commit.
