    r600g: interpret integer texture types as ints.

    For signed/unsigned with no normalisation or srgb, assume its an INT
    type texture.

It's still not rendering.

Hi Dave & Andy,

I think we have a disagreement here about what SCALED types should be.

As I understood it SCALED types should be represented as integers in memory,
but when loaded into a shader converted to floats in the range 0..2^n (in
opposite to normalized types), and that's how I used them in g3dvl.

I also added code to r600g to support those types as textures and render
target, but this code got removed before merge because I figured out why
working with normalized textures/render targets didn't got the expected
results.

@Andy: The attached patch should fix your issue, but I will delay committing it
until we have figured out how SCALED types should be really handled.

That's right if you are talking about USCALED.

OK, I can confirm it does fix it.

Without attachment 51268 applied, I see the grey area described in comment #0
but when I run
$ VDPAU_DRIVER=r600 mplayer -fs -aid 0x82 -sid 7 -vo vdpau -vc ffmpeg12vdpau
dvd://1
with the workaround applied, I get:
> mplayer: vl/vl_mpeg12_bitstream.c:980: vl_mpg12_bs_decode: Assertion `consumed <= num_bytes' failed.

I'm using Mesa from master (d7cdbc3c), mplayer is at 1.0~rc4+svn20110809 (from
debian-multimedia.org). PCI ID for the GPU 1002:9553.

Probably not related to the fix as such, but I also have problems with streams
that just stop - or (only just tested) dvd://.

For me dvd:// just hangs requiring a kill -9. It will work if I use -cache
20000.

I also just noticed that using -vo vdpau subs/control overlay will be
incorrectly positioned/sized after toggling to and back from fullscreen.
