This is always passed as zero, so let's make the code a bit easier to
grok by removing this unused argument. We still need to pass zero to the

When running a GL 2.1 program in that guest on a GLES host that uses 1D
textures then the emitted shaders must not declare 1D sampler, since they
are not supported. Instead, use 2D samplers since 1D textures are emulated
by 2D textures, and also fix the texture shader call.
Closes: #33

On an GL host set the sRGB blit framebuffer state explicitly to make virgl
behave like on a GLES host.
This does not correct the handing of sRGB completely, because the state
GL_FRAMEBUFFER_SRGB is not properly transmitted to the host. As a result
the piglits "blit texture linear_to_srgb * * *" flip.
Tests thatset "enable" failed before and pass now, and tests that set "disable"
now fail.
v2: - Move setting the fbo state out of the loop (Robert Tarasov)
- Use the blitter context to set and store the state, since it is only,
and currently we don't pass the state from the guest
relevant when the dst texture is SRGB, there is no need to disable it
- Just enforce that a source SRGB texture is always decoded when this could
be disabled

Since the framebuffer used for blits is reused, attachements must be removed

Ensure we don't blit pixels originating from outside the extents of the
source resource. To achieve this we clip the source blit region, and
update the destination blit region accordingly, while respecting scaled
blits.
This fix will allow us to introduce swizzles for some formats in
upcoming commits, and thus use the GL blitter for them, without
introducing any regressions

Update the blit shader creation code to take the destination format
swizzle into account. This involves inverting the swizzle information
and using the inverted swizzle to reorder the texel components in the
shader. The new swizzle code also removes the need for having a special
case if the destination format uses emulated alpha.
This commit temporarily removes the VIRGL_FORMAT_R8G8B8X8_UNORM special
case. Improved support for it, and other similar "ignore alpha" cases,
is added back in an upcoming commit using appropriate swizzles.
At the moment we always recreate the shader in case we have a swizzle,
but a more efficient shader caching scheme could be devised to improve
this.

Currently, we always try to create an OpenGL 3.1 context. Some
dEQP tests require an OpenGL 3.2 context (specifically, ones
that use glGetInteger64v). Let's try to create the highest
version context we can, and iterate to lower versions, i.e:
https://developer.android.com/guide/topics/graphics/opengl.html#version-check
The return code for (*create_gl_context) is a little unclear.
This patch assumes NULL is returned on failure. This should work
for GLX and EGL.
GLX:
"On failure glXCreateContextAttribsARB returns NULL and generates
an X error with extended error information"
https://www.khronos.org/registry/OpenGL/extensions/ARB/GLX_ARB_create_context.txt
EGL:
"#define EGL_NO_CONTEXT ((EGLContext)0)"
https://www.khronos.org/registry/EGL/api/1.1/EGL/egl.h
The semantics of rcbs->create_gl_context may be different, though.
