+================================================================================
+OpenGL ES 2.x support
+================================================================================
+
+SDL has support for OpenGL ES 2.x under Windows via two alternative 
+implementations. 
+The most straightforward method consists in running your app in a system with 
+a graphic card paired with a relatively recent (as of November of 2013) driver 
+which supports the WGL_EXT_create_context_es2_profile extension. Vendors known 
+to ship said extension on Windows currently include nVidia and Intel.
+
+The other method involves using the ANGLE library (https://code.google.com/p/angleproject/)
+If an OpenGL ES 2.x context is requested and no WGL_EXT_create_context_es2_profile
+extension is found, SDL will try to load the libEGL.dll library provided by
+ANGLE.
+To obtain the ANGLE binaries, you can either compile from source from
+https://chromium.googlesource.com/angle/angle or copy the relevant binaries from
+a recent Chrome/Chromium install for Windows. The files you need are:
+    
+    * libEGL.dll
+    * libGLESv2.dll
+    * d3dcompiler_46.dll (supports Windows Vista or later, better shader compiler)
+    or...
+    * d3dcompiler_43.dll (supports Windows XP or later)
+    
+If you compile ANGLE from source, you can configure it so it does not need the
+d3dcompiler_* DLL at all (for details on this, see their documentation). 
+However, by default SDL will try to preload the d3dcompiler_46.dll to
+comply with ANGLE's requirements. If you wish SDL to preload d3dcompiler_43.dll (to
+support Windows XP) or to skip this step at all, you can use the 
+SDL_VIDEO_WIN_D3DCOMPILER hint (see SDL_hints.h for more details).
+
+Known Bugs:
+    
+    * SDL_GL_SetSwapInterval is currently a no op when using ANGLE. It appears
+      that there's a bug in the library which prevents the window contents from
+      refreshing if this is set to anything other than the default value.

+*
+* This file should be included as
+*        #include <KHR/khrplatform.h>
+* by Khronos client API header files that use its types and defines.
+*
+* The types in khrplatform.h should only be used to define API-specific types.
+*
+* Types defined in khrplatform.h:
+*    khronos_int8_t              signed   8  bit
+*    khronos_uint8_t             unsigned 8  bit
+*    khronos_int16_t             signed   16 bit
+*    khronos_uint16_t            unsigned 16 bit
+*    khronos_int32_t             signed   32 bit
+*    khronos_uint32_t            unsigned 32 bit
+*    khronos_int64_t             signed   64 bit
+*    khronos_uint64_t            unsigned 64 bit
+*    khronos_intptr_t            signed   same number of bits as a pointer
+*    khronos_uintptr_t           unsigned same number of bits as a pointer
+*    khronos_ssize_t             signed   size
+*    khronos_usize_t             unsigned size
+*    khronos_float_t             signed   32 bit floating point
+*    khronos_time_ns_t           unsigned 64 bit time in nanoseconds
+*    khronos_utime_nanoseconds_t unsigned time interval or absolute time in
+*                                         nanoseconds
+*    khronos_stime_nanoseconds_t signed time interval in nanoseconds
+*    khronos_boolean_enum_t      enumerated boolean type. This should
+*      only be used as a base type when a client API's boolean type is
+*      an enum. Client APIs which use an integer or other type for
+*      booleans cannot use this as the base type for their boolean.
+*
+* Tokens defined in khrplatform.h:
+*
+*    KHRONOS_FALSE, KHRONOS_TRUE Enumerated boolean false/true values.
+*
+*    KHRONOS_SUPPORT_INT64 is 1 if 64 bit integers are supported; otherwise 0.
+*    KHRONOS_SUPPORT_FLOAT is 1 if floats are supported; otherwise 0.
