nit: get rid of this. Here and below.

[Geoff Lang, 2016/06/01 20:11:51]

I can remove it from the generator, but this generation code also generates
gles2_cmd_decoder_autogen.h

[Zhenyao Mo, 2016/06/01 20:17:44]

I think it's most likely not needed in gles2_cmd_decoder_autogen.h, but let's
not change it in this CL, to avoid complicating things.

+  GLenum texture = static_cast<GLenum>(c.texture);
+  error::Error error = DoActiveTexture(texture);
+  if (error != error::kNoError) {
+    return error;
+  }
+  return error::kNoError;

[Zhenyao Mo, 2016/05/31 01:37:22]

This is rather unfortunate that we can't just "return DoActiveTexture(texture)".
But for simplicity in code generator, I guess that's OK.

[Geoff Lang, 2016/06/01 20:11:51]

Agreed, not so simple to detect which commands do extra logic after the Do call.

Isn't this the wrong value? The function only works for 32 bit results.

[Geoff Lang, 2016/06/01 20:11:51]

Could you elaborate?  bufsize here is the number of GLint64's that can fit in
the params pointer and it looks like the ComputeMaxResults here does the right
thing (divides by sizeof(GLint64)).

[Zhenyao Mo, 2016/06/01 20:17:44]

Never mind.  I thought I read / sizeof(uint32_t), now I recheck the code, it's
not.  You are correct here.
