A logic error

[linuxaged]

in _ktxCheckHeader function (checkheader.c):

    if (header->glTypeSize != 1 ||
        header->glTypeSize != 2 ||
        header->glTypeSize != 4)
    {
        /* Only 8, 16, and 32-bit types supported so far */
        return KTX_INVALID_VALUE;
    }

i think this will be alway true.
use '&&' instead ?

You're right!! Thanks. Fixed in commit 3b3e794 on master and 3a47eb9 on incoming.

I'll open a new issue to remind me to create a big-endian KTX file.
