No S3TC/DXT compression enums #39

I wanted to switch over to this, but I have one issue: there is no definition of GL_COMPRESSED_RGBA_S3TC_DXT1_EXT or similar. Is this by design? I see there is other compression formats like BPTC and ASTC, but no DXT.

GL_COMPRESSED_RGBA_S3TC_DXT1_EXT is currently not present in glcorearb.h which is the API gl3w exports and loads.

NB: The extension that provides these formats is described here: https://www.opengl.org/registry/specs/EXT/texture_compression_s3tc.txt

To follow up, it seems that glcorearb.h is finally exposing GL_COMPRESSED_RGBA_S3TC_DXT1_EXT these days.
