DrawTransformFeedback() needs to obtain the number of vertices written
to a particular stream during the last Begin/EndTransformFeedback block.
The new driver hook returns exactly that information.
Gallium drivers already implement this by passing the transform feedback
object to the drawing function, counting the number of vertices written
on the GPU, and using draw indirect. This is efficient, but doesn't
always work:
If vertex data comes from user arrays, then the VBO module needs to
know how many vertices to upload, so we need to synchronously count.
Gallium drivers are currently broken in this case.
It also doesn't work if primitive restart is done in software. For
normal drawing, vbo_draw_arrays() performs software primitive restart,
splitting the draw call in two. vbo_draw_transform_feedback() currently
doesn't because it has no idea how many vertices need to be drawn.
The new driver hook gives it that information, allowing us to reuse
the existing vbo_draw_arrays() code to do everything right.
On Intel hardware (at least Ivybridge), using the draw indirect approach
is difficult since the hardware counts primitives, rather than vertices,
which requires doing some simple math. So we always use this hook.
Gallium drivers will likely want to use this hook in some cases, but
want to use the existing draw indirect approach where possible. Hence,
I've added a flag to allow drivers to opt-in to this call.
v2: Make it possible to implement this hook but only use this path
when necessary (suggested by Marek).

This patch implements the common support code required for the
ARB_shader_atomic_counters extension. It defines the necessary data
structures for tracking atomic counter buffer objects (from now on
"ABOs") associated with some specific context or shader program, it
implements support for binding buffers to an ABO binding point and
querying the existing atomic counters and buffers declared by GLSL
shaders.
v2: Fix extension checks. Drop unused MAX_ATOMIC_BUFFERS constant.

There is nothing in the OpenGL specification which prevents the user from
calling glGenQueries to generate a new query object while another object is
active. Neither is there anything in the Mesa implementation which prevents
this. So remove the INVALID_OPERATION errors in this case.
Similarly, it is explicitly allowed by the OpenGL specification to delete an
active query, so remove the assertion for that case, replacing it with the
necesssary state updates to end the query, (clear the bindpt pointer and call
into the driver's EndQuery hook).

The queries GEOMETRY_VERTICES_OUT, GEOMETRY_INPUT_TYPE, and
GEOMETRY_OUTPUT_TYPE (defined by GL 3.2) differ from the corresponding
queries in ARB_geometry_shader4 in the following ways:
- They use different enum values
- They can only be queried; they cannot be set.
- Attempting to query them yields INVALID_OPERATION if the program is
not linked, or lacks a geometry shader.
This patch switches us over from the ARB_geometry_shader4 behaviour to
the GL 3.2 behaviour.

This will make it easier for back-ends to share code between geometry
shader and vertex shader compilation. Also, it is renamed to
"UsesClipDistanceOut" to clarify that (a) in geometry shaders, it
refers to the gl_ClipDistance output rather than the gl_ClipDistance
input, and (b) it is irrelevant in fragment shaders.

Since gl_ClipDistance is lowered from an array of floats to an array
of vec4's during compilation, transform feedback has special logic to
keep track of the pre-lowered array size so that attempting to perform
transform feedback on gl_ClipDistance produces a result with the
correct size.
Previously, this special logic always consulted the vertex shader's
size for gl_ClipDistance. This patch fixes it so that it uses the
geometry shader's size for gl_ClipDistance when a geometry shader is
in use.
Fixes piglit test spec/glsl-1.50/transform-feedback-type-and-size.
v2: Change the type of LastClipDistanceArraySize to "unsigned", and
clarify the comment above it.

Instead of checking width==height in four places, just do it in
_mesa_legal_texture_dimensions() where we do the other width, height,
depth checks. Similarly, move the check that cube map array depth is
a multiple of 6.
This change also fixes some missing cube dimension checks for the

Remove width==height assertion in _mesa_get_tex_max_num_levels() since
that's called before the other size checks for glTexStorage.

These make it easy to convert a floating point value to a fixed point
numbers. The second parameter is the number of bits used for the
fractional part of the number.
It looks like core Mesa has similar functions already, but none that
allows an arbitrary number of fractional bits. The more generic version
is probably useful to everyone.
r600g apparently has an identical copy of the S_FIXED macro, but doesn't
include this file. I'm not sure what to do about that, so I'm just
going to leave it for now.

Fixes GL2ExtensionTests/egl_image_external/TestSimpleUnassociated.test
which is part of gles2/3 conformance suite. Here image external
textures are switched to be treated the same as 2D textures. These
can be associated with the fallback texture providing fixed sample
values of (0, 0, 0, 1).
The OES_EGL_image_external spec says:
"Sampling an external texture which is not associated with any EGLImage
sibling will return a sample value of (0,0,0,1)."
"External textures cannot be used with TexImage2D, TexSubImage2D,
CompressedTexImage2D, CompressedTexSubImage2D, CopyTexImage2D, or
CopyTexSubImage2D, and an INVALID_ENUM error will be generated if
this is attempted."
And quoting Chad:
"That's enforced in _mesa_TexImage*() by calling
legal_teximage_target(), and enforced in _mesa_TexSubImage*() by
calling legal_texsubmimage_target(). Each of the
legal_tex*image_target() functions reject external textures.
Therefore, allowing GL_TEXTURE_EXTERNAL_OES in store_texsubimage()
won't violate the above spec quote.
I think it's safe to allow GL_TEXTURE_EXTERNAL_OES in
store_texsubimage(), as long as the texture has only a single
plane. Luckily, that's the only type of external textures that
Mesa currently supports."

This provides an interface for applications (and OpenGL-based tools) to
access GPU performance counters. Since the exact performance counters
available vary between vendors and hardware generations, the extension
provides an API the application can use to get the names, types, and
minimum/maximum values of all available counters. Counters are also
organized into groups.
Applications create "performance monitor" objects, select the counters
they want to track, and Begin/End monitoring, much like OpenGL's query
API. Multiple monitors can be in flight simultaneously.
v2: Pass ctx to all driver hooks (suggested by Christoph), and attempt
to fix overallocation of bitsets (caught by Christoph). Incomplete.
v3: Significantly rework core data structures. Store counters in groups
rather than in a global list. Use their array index in the group's
counter list as the ID rather than trying to store a globally unique
counter ID. Use bitsets for active counters within a group, and
also track which groups are active so that's easy to query.
v4: Remove _mesa_ prefix on static functions; detect out of memory
conditions in new_performance_monitor(); make BeginPerfMonitor hook
return a boolean rather than setting m->Active or raising an error.
Switch to GLuint/unsigned for NumGroups, NumCounters, and
MaxActiveCounters (which also means switching a bunch of temporary
variable types). All suggested by Brian Paul. Also, remove
commented out code at the bottom of the block. Finally, fix the
dispatch sanity test (noticed by Ian Romanick).
