* It was picking the wrong clear method which is fixed now (D3D11 problem)
* added check to find such a case earlier

#ttp 331829 - Mobile Preview in Editor
#proj Engine
#branch UE4
#summary First pass of changes to remove GRHIFeatureLevel, allowing for multiple scenes with different feature levels to exist. First step towards dynamic mobile preview in the editor.
#change Added GMaxRHIFeature level which contains the highest supported feature level on this machine
#change Added a cvar "r.FeatureLevelPreview" which, when set to 1, enables a feature level selection in the quick settings menu. Not wired up to anything at the minute
#change Added a feature level variable to FScene, which is currently initialized to whatever GRHIFeatureLevel is. Accessed with GetFeatureLevel()
#change Added a helper accessor GetFeatureLevel() to FSceneView which gets the feature level from the relevant scene. Purely to reduce the amount of typing needed to get to a feature level
#change Many changes across the renderer to try and read the current feature level from the view or scene. Not everything is done yet, but this is almost all of the "easy" stuff. As there is still just a global feature level in the engine, nothing should change.

#proj core
#branch UE4
#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.

XP support is off by default and currently only supported for win32 builds using Visual Studio 2013
I have updated a lot of platform atomic calls to use 32 bits as 64 is not supported on windows xp.
Added extra checks in d3d11 to ensure that these cached shaders are for that platform.
Added a validity check to the TextInputMethodSystem before we try and process input.
128 bit atomics disabled for header generator. Causes issues with xp compilation. Reviewed by Steve Robb.
Texture Memory size stats changed to from bytes to kilobytes to satisfy dependency for 32 bit atomics.
Note: OpenGL is the default RHI for WindowsXP.

Moved functions to check for and select Compressed Audio Info class to the audio device as the audio formats are not accessible in cooked builds (and shouldn't really need to be either).

#change - Clear and resolve whole shadow targets rather than using subrects.
#change - RHISetRenderTargets sets the viewport to the size of the depth buffer if there is no colour target

Added an audio format for Opus, which also required a resampler to make sure that all imported sounds are converted to a compatible sample rate.
Added the speex resampler from the opus tools package to the third party source, including built libraries for windows and mac.
Changed FVorbisAudioInfo so that it inherits from an interface for any kind of compressed audio, which can be used everywhere instead of being wrapped in #WITH_VORBIS.
Added FOpusAudioInfo to decompress Opus data, not sure at this point whether it's only going to be used for streaming audio but works for non-streamed playback.
