perspectiveorigin001 
= 

perspectiveorigin  0px center('center' computes to '50%' in vertical position)
 The 'perspectiveorigin' property set 'center' computes to 50% for the vertical position.

perspectiveorigin002

perspectiveorigin  50% top('top' computes to '0%' in vertical position)
 The 'perspectiveorigin' property set 'top' computes to 0% for the vertical position.

perspectiveorigin005

perspectiveorigin  left 50%('left' computes to '0%' in horizontal position)
 The 'perspectiveorigin' property set 'left' computes to 0% for the horizontal position.

perspectiveorigin006

'perspectiveorigin' and translate()
 This tests that 'perspective' and 'perspectiveorigin' have the same effect as an appropriately calculated sequence of translate() and perspective(). The reference file's body has a width of 400px and a height of 100px, so the perspectiveorigin should be (200, 50). The transformorigin is 'top', which works out to (50, 0). Thus we translate by (150, 50) to get the right origin.

= ≠ ≠ ≠ 

perspectiveorigin
 This tests that 'perspectiveorigin: 0 0' is the same as 'perspectiveorigin: top left', different from no 'perspectiveorigin', and different from no perspective or no transform.
