Gl_400_fbo_multisample, Gl_430_direct_state_access_ext, Gl_400_texture_derivative

[elect86]

C and Java fails.

Shader status invalid: 0(20) : error C5229: Argument 1 for interpolateAtSample must have no component selection

OpenGL Error(GL_INVALID_OPERATION): initProgram

Same for interpolateAtOffset

probabily nvidia glsl compiler bug

[elect86]

Temporary fix (valid only for interpolateAtSample)

this means only for gl-400-fbo-multisample and gl-430-direct-state-access-ext

in vert
{
    vec2 Texcoord;
    //sample vec2 Texcoord;
} Vert;

layout(location = FRAG_COLOR, index = 0) out vec4 Color;

void main()
{
    Color = texture(Diffuse, interpolateAtSample(Vert.Texcoord, gl_SampleID));
    //Color = texture(Diffuse, Vert.Texcoord);
}

interpolateAtSample works on linux, although through recompilation..
