    • Update eglext.h. · 88f18d01
      Jamie Madill authored 
      Also move the ANGLE modifications to eglext.h to a separate file
so we can more easily update and maintain the official header.

This is in preparation for adding the new program cache control
extension.

    • Clip TextureD3D_2D::copyImage to framebuffer. · 95ba174e
      Frank Henigman authored 
      WebGL CopyTexImage needs to zero the part of the texture corresponding
to area outside the framebuffer, so we zero the whole texture then clip
the read area.
The clipping also avoids problems with code lower down that isn't prepared
for read areas not entirely within the framebuffer.

Enable corresponding test.

    • Improve Debugging Strings · 6cad5667
      Brandon Jones authored 
      This change replaces common string literals used for
error messages with const string variables mapped in
a new header file.

Additionally, more validation for WebGL naming scenarios
has been added, along with unit tests.

    • Clip FramebufferGL::readPixels to framebuffer. · fa36c330
      Frank Henigman authored 
      In GL, ReadPixels() is allowed to modify memory that corresponds to
pixels outside the framebuffer.
In WebGL it must not do that, so clip the read area to the framebuffer.

Enable corresponding test.

    • HLSL: Disambiguate between struct function parameters · 088031e6
      Olli Etuaho authored 
      Structs with different names but identical members are treated as
ambiguous by the native HLSL compiler when looking up user-defined
functions. Add the struct name to the function name to work around
this limitation.

    • Re-land: Don't expose non-conformant multisampling modes on GL · 50c562de
      Olli Etuaho authored 
      Re-landing with a fallback for failed internal format queries to work
around issue seen on Shield TV. Also fixed wrong handling of integer
RG formats in isRequiredRenderbufferFormat.

Some NVIDIA GL drivers expose non-conformant multisampling modes. The
conformance of multisampling modes can be queried using the extension
NV_internalformat_sample_query. Use it to filter out the
non-conformant modes from the modes that are exposed by ANGLE.

The MAX_SAMPLES value and other similar values stored in caps also
need to be lowered to match the maximum number of samples exposed
for required formats.

There seems to be an NVIDIA driver bug related to querying
STENCIL_INDEX8 multisample format. Work around this by querying
DEPTH24_STENCIL8 instead.

There's also some confusion around whether RGB9_E5 should be
renderable. Once the floating point texture extensions got rolled
into the core GL spec, it was eventually made clear that RGB9_E5
is intended not to be renderable. The extension specs that predate
float textures in the core spec do suggest that it would be
renderable, but in practice drivers that advertise the extension
strings don't reliably implement RGB9_E5 as renderable. Solve this
by disabling it as a renderable format and adding an explanatory
comment.

    • Clean up redundant initialization of gl_Position · b12040c4
      Olli Etuaho authored 
      In case gl_Position is statically used in the input shader, setting
the INIT_OUTPUT_VARIABLES flag will initialize gl_Position. Avoid
redundant initialization of gl_Position in this case.

Includes cleaning up memory management in InitOutputVariables_test:
all the pool-allocated variables will be freed at the end of each test
when the memory pool is cleared, so manual memory management is not
needed.

Also includes making the zero node check used in unit tests stricter
so that the tests are more reliable and moving it to
ShaderCompileTreeTest.h so that it can be reused in the future.
