RELEASE NOTES
* The DirectXTex library does not support block compression or decompression of mipmapped non-power-of-2 textures,
although DDSTextureLoader will load these files correctly if the underlying device supports it.

* The DirectXTex library only supports CLAMP filtering, and does not yet support MIRROR or WRAP filtering

for 3D volume mipmap-generation. [CodePlex issue 642]
* The WIC conversion cases currently ignore TEX_FILTER_SRGB_IN and TEX_FILTER_SRGB_OUT out, which results in incorrect sRGB handling in
a number of cases. [CodePlex issue 643]
* Due to the underlying Windows BMP WIC codec, alpha channels are not supported for 16bpp or 32bpp BMP pixel format files. The Windows 8
version of the Windows BMP WIC codec does support 32bpp pixel formats with alpha when using the BITMAPV5HEADER file header. Note the updated
WIC is available on Windows 7 SP1 with KB 2670838 installed.
* The WIC conversion cases currently ignore TEX_FILTER_SRGB_IN and TEX_FILTER_SRGB_OUT out.
* For the DXGI 1.1 version of DirectXTex, 4:4:4:4 pixel format DDS files are always expanded to 8:8:8:8 upon load since DXGI 1.0
and DXGI 1.1 versions of Direct3D do not support these resource formats. The DXGI 1.2 versions of DirectXTex and DDSTextureLoader
make use of the DXGI_FORMAT_B4G4R4A4_UNORM format instead.
