/*
	Renderer attribute dynamics test

	For each Renderer attribute, dynamics are tested
	by the algorithm described below.

	In order to only implement the attribute-setting and
	drawing code once per attribute type, this algorithm is
	actually implemented in a loop that is controlled by
	an array of flags (see loop_control, below).  The
	steps accomplished by each pass through the loop are
	labelled here.

	{
		PASS 0
		set attribute to value 1 (while Renderer is idle)
		bind (to a window)
		draw something with value 1 (image A)

		PASS 1
		set attribute to value 2 (while Renderer is active)
		draw something (image A)
		- if the attribute has immediate dynamics,
		  this will be done with the value 2;
		  if it has deferred dynamics, drawing
		  will be done with value 1
		unbind

		PASS 2
		bind
		draw something (image B)
		- even deferred attributes will use value 2 here
		unbind
	}

	Note that "attributes" includes all the specified Renderer
	attributes, and LUT and Nameset contents as well.

	Note also that some Renderer attributes require two archived images
	to demonstrate, others can use a subframe per setting, and yet others are
	demonstrated by drawing several primitives in one sub-frame of 
	one image.  When sub-frames can be used, the window is typically divided 
	into four sub-frames which are then archived together as an image.

	For XSystem, text bundle and text font table dynamics are done in a 
	separate test with the same organization.  This allows only
	that test to be rearchived if text rendering suffers pixelitis 
	due to floating point libraries or for other reasons.
    There are not two separate tests for susPEX.

	These constants determine the order in which the
	attributes are tested.  The ordering is important
	because tests of later attributes assume that earlier
	ones work correctly.

	HLHSR mode is first because once a Z buffer has been 
	allocated, it remains associated with the Renderer.
	Clearing functionality is tested next because it is also
	heavily used.  Viewport setting is also relied on for
	subframe operation.

	The attr_control array describes variations in the
	testing algorithm to test each particular attribute.
	The first few attributes require an image per setting.
	Attributes starting with NPC subvolume are tested
	using subframes.  Attributes starting with ?? can be
	tested in single subframes, allowing several attributes
	to be tested per archived image.

	FIRST_ATTR and LAST_ATTR determine the attributes that
	are tested.
