[whatwg] Canvas lack of drawString method (p.s.)

[Stefan Haustein]

James,

the second image exposes exactly the problem that an alignment parameter 
would solve:

"TR" and "1/2pi" could be drawn aligned "baseline right" to the 
references point on the y-axis.
"0.97" and "pi" could be drawn aligned "top center" to the reference 
points on the x-axis.

The badly rendered example image looks like single characters are placed 
at fixed positions out of context.
Of course, this will lead to problems not only when the fonts are 
substituted, but also for the slight differences in font sizes...

Best regards,
Stefan
