There are certain advantages to using uint8_t internally such as
well-defined arithmetic on all platforms. However, interfaces that
work in terms of raw data should use a void* type.

Despite the name, it could only be used if you immediately wrote to the
pointer. Noboby was using it outside of one test, so clearly this
behavior wasn't that useful. Instead, make it return an offset into the
data buffer so that the result isn't invalidated if you later write to
the blob. In conjunction with blob_overwrite_bytes(), this will be
useful for leaving a placeholder and then filling it in later, which
we'll need to do for handling phi nodes when serializing NIR.

- Fix return value (s/MESA_FORMAT_NONE/false/) (Anuj)
- Move _mesa_tex_format_from_format_and_type() just

- Explain better the array alignment restriction (Anuj)
- Do not bail out in case of gl_pixelstore_attrib::ImageHeight,

- Support 1D_ARRAY by flipping depth, width and y, z (Ken).
v3 (Topi Pohjolainen):
- Contrary to v2, do not try to handle
gl_pixelstore_attrib::ImageHeight. Currently there are no
tests in piglit or cts for it. One could possibly copy or
modify tests/texturing/texsubimage.c. There, however, seems
to be number of corner cases to consider. Moreover, current
meta path applies the packing height for both source and
targets when determining the offset. This would probably
require re-visiting also.
v4 (Topi Pohjolainen): Rebased on top of merged drm-bacon
v5 (Jason Ekstrand):
- Move to brw_blorp.c
- Significant refactoring
- Fixed 1-D array textures
- Simplified handling of PBOs vs. CPU data.
- Handle gl_pixelstore_attrib::ImageHeight. It turns out there are

The GL_EXT_texture_sRGB_decode spec says:
"The conversion of sRGB color space components to linear color space is
always performed if the texel lookup function is one of the texelFetch
builtin functions.
Otherwise, if the texel lookup function is one of the texture builtin
functions or one of the texture gather functions, the conversion of sRGB
color space components to linear color space is controlled by the
TEXTURE_SRGB_DECODE_EXT parameter.
If the TEXTURE_SRGB_DECODE_EXT parameter is DECODE_EXT, the conversion
of sRGB color space components to linear color space is performed.
If the TEXTURE_SRGB_DECODE_EXT parameter is SKIP_DECODE_EXT, the value
is returned without decoding. However, if the texture is also accessed
with a texelFetch function, then the result of texture builtin functions
and/or texture gather functions may be returned with decoding or without
decoding."
This patch makes i965 force sRGB decoding for any textures accessed via
texelFetch(). If textures are accessed via texelFetch() and a regular
texture access function, this will affect the other ones too - which is
fine - it's undefined according to the last paragraph quoted.
We could make both work, but we'd have to emit multiple SURFACE_STATEs,
and have two binding table sections, like we do for texture gather hacks
on older platforms.

Drivers that use Meta are happily using blitting data using texelFetch

makes GL_SKIP_DECODE_EXT not necessarily work with texelFetch.
As a hack, just unset the texture_used_by_txf bitfield so we can
continue with the old desired behavior.

If an RS blit is done with source exactly the same as destination, and
the hardware supports this, do an in-place resolve. This only fills in
tiles that have not been rendered to using information from the TS.
This is the same as the blob does and potentially saves significant
bandwidth when doing i.MX6qp scanout using PRE, and when rendering to
textures (though here using sampler TS would be even better).
