As we do for NV12, let's also clear packed YUV formats to black instead
of zero. Avoids unexpected green screens.

We don't do the "black != zero" clearing for dumb buffers, so let's not
use them for YCbCr framebuffers.

Always populate the plane_bpp[] stuff, and use named initializers so
that we can actually see what's being set to what.

Meh, I wish you exported m(row,col) so that I don't have to think about
the matrix layout.

Wiki gives
y = kr * R + kg * G + kb * B
cb = 0.5 * (B - y) / (1 - kb)
cr = 0.5 * (R - y) / (1 - kb)
2*cb*(1-kb) = (B - (kr * R + kg * G + kb * B))
= -kr * R - kg * G + (1 - kb) * B
2*cb = -kr/(1-kb) * R + -kg/(1-kb) * G + B
And the factor of 2 falls out in the range conversion.
Ok, you've convinced me the maths checks out.

Probably horribly inefficient (not that the original code tried to be
particularly efficient), but at least this is now pretty generic so
it'll be super easy to add other color encodings and whatnot.
v2: Rebase
v3: Deal with the new color_encoding/range enums

Keep the comment about averaging tl+br. Why only 2 points btw?

Lazy I guess. Hmm. Somehow this doesn't even look right to me now. I
think I'll have to actually figure out what I was doing here, and test
it on actual hardware.

Probably horribly inefficient (not that the original code tried to be
particularly efficient), but at least this is now pretty generic so
it'll be super easy to add other color encodings and whatnot.
v2: Rebase
v3: Deal with the new color_encoding/range enums
v4: Fix the code to actually work, and do things in 2x2 blocks
Keep the chroma siting comment and pimp it up a bit

Reuse the __convert() cairo stuff to support packed YCbCr framebuffers.
v2: Allow odd fb width since some tests want it
v3: Use igt_memcpy_from_wc()
v4: Rebase due to color_encoding/range enums

Hmm. I think it's correct.
swizzle[] tells us in which offset in the macropixel we find the
component. The index determines which component we want.
swizzle[0] = offset of Y0
swizzle[1] = offset of U
swizzle[2] = offset of Y1
swizzle[3] = offset of V
so for the vyuy case the macropixel layout will be:
byte: 0 1 2 3
swizzle[3] swizzel[0] swizzle[1] swizzle[2]
V Y0 U Y1
Seems to make some sense, at least to me.

So I was reading it as the inverse mapping,
swizzle_vyuy:
byte 0 = v, read offset 1
byte 1 = y, read offset 2
byte 2 = u, read offset 3
byte 3 = y, read offset 0
but the incoming offsets are yuyv, so I read { 1, 2, 3, 0 } as uyvy.
From thinking that
swizzle_rgba = { 0, 1, 2, 3 }
swizzle_rrrr = { 0, 0, 0, 0 }

Reuse the __convert() cairo stuff to support packed YCbCr framebuffers.
v2: Allow odd fb width since some tests want it
v3: Use igt_memcpy_from_wc()
v4: Rebase due to color_encoding/range enums
v5: Follow the fixed nv12 code

Make igt_fb be aware of the color encoding/range. For now
we still hardcore everything to BT.709 limited range though.
