According to the OpenGL ES 3.2 spec's description of GenerateMipmap:
"An INVALID_OPERATION error is generated if the levelbase array was not
specified with an unsized internal format from table 8.3 or a sized
internal format that is both color-renderable and texture-filterable
according to table 8.10."
Similar text exists in the ES 3.0 specification as well.
Our existing rules are pretty close, but miss a few things. The
OpenGL specification actually doesn't have any text about internal
format checking - our existing code comes from a Khronos bug report.
The ES 3.x spec provides a clearer description.

OpenGL ES 3.x contains a table of sized internal formats and their
required properties. In particular, each format is marked as
"Color Renderable" or "Texture Filterable".
This patch introduces two functions that can be used to query the
information from that table.

Wide points and lines are not supposed to be clipped by the viewport.
Rather, they should be rendered, and any fragments outside of the
viewport should be discarded.
The traditional use case for this behavior is rendering moving wide
point particles. When the center of the point approaches the viewport
edge, clipping would make it pop out of view early.

We're about to start allowing wide points/lines whose vertices are
outside the viewport past the clipper. This scissoring hack ensures
that any fragments generated are still restricted to the viewport.
It is not necessary on Gen8+ as those platforms already discard
fragments which are outside the viewport.

Thanks to James Legg for finding this!
From the ARB_tessellation_shader spec:
"The number of isolines generated is derived from the first outer
tessellation level; the number of segments in each isoline is
derived from the second outer tessellation level."
According to the PRM, "TF.LineDensity determines # lines" while
"TF.LineDetail determines # segments". Line Density is stored at
DWord 6, while Line Detail is at DWord 7. So, they're not reversed
like they are for triangles and quads.

Patch provides a default for a set pbuffer surface size when
EGL_LARGEST_PBUFFER is used by the client. MIN2 macro is moved
to egldefines so that it can be shared.
Fixes following Piglit test:
egl-create-largest-pbuffer-surface
From EGL 1.5 spec:
"Use EGL_LARGEST_PBUFFER to get the largest available pbuffer
when the allocation of the pbuffer would otherwise fail."
Currently there exists no API to query largest available pixmap size
using xlib or xcb so right now this seems most straightforward way to
ensure that we fulfill above API and also we don't attempt to allocate
'too big' pixmap which might succeed on server side but not work in
practice when driver starts to use it as a texture.

The bitcasting which is possible with shader images (and texture views?)
requires that when the user specifies a sized internal format for a
texture, we really allocate that format. To this end:
(1) find_exact_format should ignore sized internal formats and
(2) some of the entries in the mapping table corresponding to sized
internal formats are reordered to use an RGBA format instead of
a BGRA one.
This fixes arb_shader_image_load_store-bitcast in the (work in progress)
ARB_shader_image_load_store implementation for radeonsi.
v2: don't change the mapping of GL_RGB10: the change caused a regression
because it preferred a format with an alpha channel, and GL_RGB10

In GL 4.4+ there is no guarantee that interpolation qualifiers will
match between stages so we cannot safely pack varyings using the
current packing pass in Mesa.
We also disable packing on outerward facing interfaces for SSO
because in ES we need to retain the unpacked varying information
for draw time validation. For desktop GL we could allow packing for
SSO in versions < 4.4 but its just safer not to do so.
We do however enable packing on individual arrays, structs, and
matrices as these are required by the transform feedback code and it
is still safe to do so.
Finally we also enable packing when a varying is only used for
transform feedback and its not a SSO.
This fixes all remaining rendering issues with the dEQP SSO tests,
the only issues remaining with thoses tests are to do with validation.
Note: There is still one remaining SSO bug that this patch doesn't fix.
Their is a chance that VS -> TCS will have mismatching interfaces
because we pack VS output in case its used by transform feedback but
don't pack TCS input for performance reasons. This patch will make the
situation better but doesn't fix it.
V4: fix out of order function params after rebase, make sure packing
still disabled in tess stages. Update comments as to why we disable
packing on SSO.
V3: ES 3.1 *does* require interpolation to match so don't disable
packing there. Rebased on master rather than on enhanced layouts
component packing series.
V2: Make is_varying_packing_safe() a function in the varying_matches
class, fix spelling (Matt) and make sure to remove the outer array
when dealing with Geom and Tess shaders where appropriate.

instruction destination bitsize.
