    The OpenGL 4.4 beta driver had a regression where we became too restrictive with samplers in structs. Basically the spec, in the absence of bindless texture, only allows samplers to be declared as...

    I was not able to reproduce this. wglGetProcAddress("wglSwapIntervalEXT") seems to return a non-NULL pointer for me. What GPU are you using?

    1) This is a bug we'll fix asap.
    2) You could use uint(uintBitsToFloat(pos.length())) as a work around.
    3) It should be pos.length(). pos.length probably produces a compile error.
    4) I'm not sure...
