I don't know if anyone else is seeing this, but there's a bug in how 
the rotated button is drawn whenever its angle is some multiple of 90 
degrees:

90: text normal, button is a very small circle, like a radio button, 
but clickable region is as wide as button should be
180: Button is normal width, but has no rounded ends - just two 
straight line top and bottom borders. Clickable region is as it should 
be.
270: text normal, button is a combination of the two above - 
orientation is off by 90 degrees (i.e., it's horizontal when it should 
be vertical, and its extent is only as wide as the button is tall. No 
rounded corners, just top and bottom borders.
360: normal

all other angles are correct, and this pattern repeats as you cycle.
