I ran across this while running a glGenerateMipmap() test._meta_GenerateMipmap sets MESA_META_TRANSFORM, which causes _mesa_meta_begin to try and set a default orthographic projection. Unfortunately, if the drawbuffer isn't set up, ctx->DrawBuffer->Width and Height are 0, which just causes an GL_INVALID_VALUE error. Fixes oglconform's fbo/mipmap.automatic, mipmap.manual, and mipmap.manualIterateTexTargets.
