  			0.5in : 'top'
		+
  			0.5in : 'margin-top'
		+
  			0     : 'border-top-width'
		+
  			0     : 'padding-top'
		+
  			1in   : 'height' (used width) / (intrinsic ratio)
		+
  			0     : 'padding-bottom'
		+
  			0     : 'border-bottom-width'
		+
  			0.5in : 'margin-bottom'
		+
  			1in   : 'bottom'
		===========
  			436px  : height of containing block (0px)

		So, bottom has to be ignored and forced to have the value that
		will balance the equation. So, this brings up

  			0.5in : 'top'
		+
  			0.5in : 'margin-top'
		+
  			0     : 'border-top-width'
		+
  			0     : 'padding-top'
		+
  			1in   : 'height' (used width) / (intrinsic ratio)
		+
  			0     : 'padding-bottom'
		+
  			0     : 'border-bottom-width'
		+
  			0.5in : 'margin-bottom'
		+
  			(solve): 'bottom'
		===================
 			240px  : height of containing block (0px)

  			So the solved bottom value should be -240px
