/* Direct3D 11.x shaders

   SDL's shaders are compiled into SDL itself, to simplify distribution.

   All Direct3D 11.x shaders were compiled with the following:

   fxc /E"main" /T "<TYPE>" /Fo"<OUTPUT FILE>" "<INPUT FILE>"

     Variables:
     - <TYPE>: the type of shader.  A table of utilized shader types is
       listed below.
     - <OUTPUT FILE>: where to store compiled output
     - <INPUT FILE>: where to read shader source code from

     Shader types:
     - ps_4_0_level_9_1: Pixel shader for Windows 8+, including Windows RT
     - vs_4_0_level_9_1: Vertex shader for Windows 8+, including Windows RT
     - ps_4_0_level_9_3: Pixel shader for Windows Phone 8
     - vs_4_0_level_9_3: Vertex shader for Windows Phone 8
   

   Shader object code was converted to a list of DWORDs via the following
   *nix style command (available separately from Windows + MSVC):

     hexdump -v -e '6/4 "0x%08.8x, " "\n"' <FILE>
