    • Add a test for flat shader 'provoking vertex'. · d55d283c
      Jamie Madill authored 
      The provoking vertex, or leading vertex, is the vertex in a triangle
which produces the value that gets used for a flat-shaded triangle.
Flat shading means the same value gets used for the entire triangle.

It seems as though D3D and OpenGL have different definitions of which
vertex is the leading/provoking one; GL says it is the *last* vertex
of a primitive, while while D3D says it is the first.

Additional complexity comes about from triangle strips, which switch
winding order, and primitive restart, which defines new primitives in
the middle of prior primitives.

    • Fix parsing integers larger than 0x7FFFFFFF · f541f529
      Olli Etuaho authored 
      Parsing should accept all values between 0 and 0xFFFFFFFF as specified in
ESSL 3.00 section 4.1.3.

When a signed literal is parsed, it's interpreted as if it specifies the
bit pattern of a two's complement integer. For example, parsing
"0xFFFFFFFF" results in -1. Decimal literals behave the same way, so for
example parsing "3000000000" results in -1294967296.

This change affects parsing of literals in ESSL 1.00 as well. In ESSL
3.00, an out-of-range integer literal now generates a compiler error.

Unit tests are added based on examples in the ESSL 3.00 spec and one
example in GLSL 4.5 spec that ESSL should match.
