If a shader uses TGSI_INTERPOLATE_LOC_SAMPLE, we need to emit
the "sample"-keyword for the input-variable in the fragment
shader.
Since the "sampler"-keyword is a GLSL 4.00 feature, this
requires us to enable GL_ARB_gpu_shader5. Unfortunately, opting
in carefully on this is a bit trickier than for most other
extensions, because we patch up vertex, geometry or tesselation
evaluation shader outputs to match the fragment shader inputs.
Since the previous patch adds padding for the require-statement
directly after the #version string, we can just overwrite that
padding with the require statement.

This adds the renderer support for exposing texture views.
The change adds support to sampler views and surfaces for the backing
object to be a separately allocated textureview instead of the actual
resource. It also adds support for parsing the updated packet where
we put the sampler view target in the top 8 bits of the format,
which should be safe as up until now it's always 0.
This doesn't do the final enable of the extension, but it will
cause us to use views in a few places we didn't before so could have
some other side effects
v2: check for buffers on surface creation, reword comment
to better explain if statement.
v3: fix logic bug (Gert). This uncovered a wierd corner case, possibly
due to how the state tracker allocates textures, but it tries to create
a surface with more layers than there are, I think it then reallocate
the whole texture object in the guest and it works out in the end,
this adds check to catch this, and to avoid creating a texture view
in that case.
v4: realise the problem with v3 was 3D textures and use
util_max_layer to fix the logic properly.

In the copy fallback, when a texture can not be rendered, the data that resides
in the backing iovec needs to be used. For the non-zero levels of mip-map textures
the data is located at an offset. This patch adds storing this offset and using it
when data is read from the backing iovec and updating the dst iov. We limit the

On GLES a multi-sample FBO region can only be blit to an non multi-sample
region if the source and the target rectangle are the same. The fallback
using GL and shaders doesn't work if a stencil buffer is involved, because
writing to a stencil buffer from a shader is usually not supported (i.e.
the extension ARB_shader_stencil_export is not available).

actual target FBO afterwards.
