  26  * Tests NamedRenderbufferStorage* functions to see if they behaves in the
  27  * expected way, throwing the correct errors, etc. Also test
  28  * glGetRenderbufferParameteriv.
  29  *
  30  * From OpenGL 4.5, section 9.2.4 "Renderbuffer Objects", page 298:
  31  *
  32  * "void NamedRenderbufferStorageMultisample(uint renderbuffer, sizei samples,
  33  *                                           enum internalformat,sizei width,
  34  *                                           sizei height );
  35  *
  36  * [...]
  37  * For NamedRenderbufferStorageMultisample, renderbuffer is the name of the
  38  * renderbuffer object. internalformat must be color-renderable,
  39  * depth-renderable, or stencilrenderable (as defined in section 9.4). width
  40  * and height are the dimensions in pixels of the renderbuffer. Upon success,
  41  * RenderbufferStorageMultisample deletes any existing data store for the
  42  * renderbuffer image, and the contents of the data store are undefined.
  43  * RENDERBUFFER_WIDTH is set to width, RENDERBUFFER_HEIGHT is set to
  44  * height, and RENDERBUFFER_INTERNAL_FORMAT is set to internalformat.
  45  * If samples is zero, then RENDERBUFFER_SAMPLES is set to zero. Otherwise
  46  * samples represents a request for a desired minimum number of samples. Since
  47  * different implementations may support different sample counts for
  48  * multisampled rendering, the actual number of samples allocated for the
  49  * renderbuffer image is implementation-dependent. However, the resulting value
  50  * for RENDERBUFFER_SAMPLES is guaranteed to be greater than or equal to
  51  * samples and no more than the next larger sample count supported by the
  52  * implementation. A GL implementation may vary its allocation of internal
  53  * component resolution based on any *RenderbufferStorageMultisample parameter
  54  * (except target and renderbuffer), but the allocation and chosen internal
  55  * format must not be a function of any other state and cannot be changed once
  56  * they are established.
  57  *
  58  * Errors
  59  * An INVALID_ENUM error is generated by RenderbufferStorageMultisample
  60  *  if target is not RENDERBUFFER.
  61  * An INVALID_OPERATION error is generated by NamedRenderbufferStorageMultisample
  62  *  if renderbuffer is not the name of an existing renderbuffer object.
  63  * An INVALID_VALUE error is generated if samples, width, or height is negative.
  64  * An INVALID_OPERATION error is generated if samples is greater than the
  65  *  maximum number of samples supported for internalformat (see
  66  *  GetInternalformativ in section 22.3).
  67  * An INVALID_ENUM error is generated if internalformat is not one of the
  68  *  color-renderable, depth-renderable, or stencil-renderable formats defined
  69  *  in section 9.4.
  70  * An INVALID_VALUE error is generated if either width or height is greater
  71  *  than the value of MAX_RENDERBUFFER_SIZE.
  72  *
  73  * void NamedRenderbufferStorage(uint renderbuffer, enum internalformat,
  74  *                               sizei width, sizei height);
  75  * are equivalent to [...] NamedRenderbufferStorageMultisample(renderbuffer, 0,
  76  * internalformat, width, height);"
