    • Capture/Replay: Implement mid-execution replay. · 6c7208f9
      Jamie Madill authored 
      Mid-execution replay starts the replay from a specific start frame
instead of frame 0. Integration tests will then run between the start
and end frames. This lets us make much smaller reproduction cases from
large benchmarks or applications.

We implement mid-execution replay via a cpp "Setup" function. The
replay test will run the setup function before the starting frame. Test
execution proceeds normally after setup.

Currently we do not implement mid-execution capture. We run capture on
all frames. Including frames before the start frame. We do this to
intercept compiled shaders and programs for easier caching. This could
be changed in the future to also start capture mid-execution. Mid-
execution capture might require using ProgramBinary calls to capture
shader and program data.

Many captures are unimplemented. Several comments indicate missing
functionality. There's a lot we can add as we explore replaying more
complex applications and higher GL versions. We will also need some
kind of state reset functionality so we can run the replay in a loop.

    • Capture/Replay: Capture GetFloatv params. · b68a279c

      Was used in the mip map ANGLE sample. Add a new helper function that we
can use for multiple captures.

    • Capture/Replay: Only convert GLES 2 GLenums to string. · a576e0d4
      Jamie Madill authored 
      Previously the enum conversion script would convert all enums in gl.xml
including those for desktop GL. When replaying from a CPP file we would
sometimes try to use enum values that only are exposed in desktop GL.

One example is GL_TEXTURE_MAX_ANISOTROPY/GL_TEXTURE_MAX_ANISOTROPY_EXT.
GLES only has the "EXT" version. Desktop uses the core version. This
was breaking a replay sample that used the EXT enum.

Fix this by a) including the anisotropy extension in registry_xml and
b) updating the enum script to only parse GLES 2 entries. In the future
we could improve the situation by auto-generating a header that defines
exactly the enums we need for ANGLE.

Also updates the enum helper to use uppercase enum values.
