* Draw some different kinds of stimuli using cm as units and verify size.
* Some stimuli aren't the actual expected size. Adjust the parameters
so that they are the size that you want.
* Pro: draw different kinds of stimuli using deg and verify whether they
have the expected size. (hint: math.tan, math.radians)
* Pro: textStims are smaller than the expected size. The relationship is
however approximately linear. Determine the linear function that makes
the actual size correspond to the specified size. Do you think it would
be general across monitors? And/or general across fonts?
