Hi Ian, 
Thanks for your comments.

OK. I will add it.

Yes. I find some similar tests named in this way. I will change it to getteximage-invalid-format-for-packed-type.c.

OK. Added it.

OK. Add it.

Can you please tell me what is the expected whitespace?

Do you mean also test other types like GL_UNSIGNED_BYTE_3_3_2, GL_UNSIGNED_BYTE_2_3_3_REV...? If so I will add them in the next patch update.

OK. I will change it.

OK. Thanks.
