    • Support writing initializers using HLSL literal syntax · 18b9deb4
      Olli Etuaho authored 
      Instead of using constructor functions to initialize variables, it is
better to use literal initializer syntax provided by HLSL when it is
possible. This way shader complexity is reduced and constant array
initialization doesn't have to go through as many AST transformations.

Before this patch, vec4 initialization would result in the following
kind of HLSL:

float4 f = float4(1.0, 2.0, 3.0, 4.0);

After this patch, it will be:

float4 f = {1.0, 2.0, 3.0, 4.0};

Before this patch, vec2 array initialization would result in the
following kind of HLSL:

float2 f[2] = {0, 0, 0, 0};
angle_construct_into_2_float2(f, float2(1.0, 2.0), float2(3.0, 4.0));

After this patch, it will be:

float2 f[2] = {1.0, 2.0, 3.0, 4.0};
