glBindSamplers binds samplers from an array of existing sampler objects to a specified number of
       consecutive sampler units.  count specifies the number of sampler objects whose names are stored in the
       array samplers. That number of sampler names is read from the array and bound to the count consecutive
       sampler units starting from first.

       If the name zero appears in the samplers array, any existing binding to the sampler unit is reset. Any
       non-zero entry in samplers must be the name of an existing sampler object. When a non-zero entry in
       samplers is present, that sampler object is bound to the corresponding sampler unit. If samplers is NULL
       then it is as if an appropriately sized array containing only zeros had been specified.

       glBindSamplers is equivalent to the following pseudo code:

               for (i = 0; i < count; i++) {
                   if (samplers == NULL) {
                       glBindSampler(first + i, 0);
                   } else {
                       glBindSampler(first + i, samplers[i]);
                   }
               }

       Each entry in samplers will be checked individually and if found to be invalid, the state for that
       sampler unit will not be changed and an error will be generated. However, the state for other sampler
       units referenced by the command will still be updated.

GL_INVALID_OPERATION is generated if first + count is greater than the number of sampler units supported
       by the implementation.

       GL_INVALID_OPERATION is generated if any value in samplers is not zero or the name of an existing sampler
       object.

glBindSamplers is available only if the GL version is 4.4 or higher.

first
           Specifies the first sampler unit to which a sampler object is to be bound.

       count

       samplers
           Specifies the address of an array of names of existing sampler objects.
