[Public WebGL] Should GLfloat and GLclampf be typedefs for "unrestricted float"?

[Boris Zbarsky <bzbarsky@MIT.EDU>]

I just tried updating Firefox to handle "float" per WebIDL spec. 
Specifically, attempts to pass non-finite floats to an argument that 
takes "float" are supposed to throw; "unrestricted float" is the type 
that allows all floating-point values.

There are two tests in the WebGL test suite that fail with this change. 
 Specifically, 
https://www.khronos.org/registry/webgl/sdk/tests/conformance/misc/type-conversion-test.html 
passes in NaN for arguments that take a "float" in a bunch of places. So 
does 
https://www.khronos.org/registry/webgl/sdk/tests/conformance/more/conformance/quickCheckAPI-L_S.html 
in a few spots.

What's the expected behavior?  Is this a bug in the tests or in the 
spec?  To be consistent with the tests, the spec should probably use 
"unrestricted float" in place of "float"...
