same color shows up different in graphics_array

[dkrenn]

The code

g = circle((0,0),1,rgbcolor='red',fill=True, alpha=0.5)
graphics_array([g,g,g]).show()

produces three circles, the first two with color 0xFF7F7F (html-color-code), the third one with color 0xFF3F3F (html-color-code). But all three should have the same color.

Huh, that's interesting. Apparently the alpha is not propogated to the last one.

In fact, there is another manifestation of this there.

Replying to [comment:3 @eviatarbach]:
> This is also a problem with other options, such as tick_formatter, ticks, and axes_labels. They are only applied to the last graphic; see attached image produced by the following code:
> graphics_array([plot(sin(B*x), xmin=-2*pi, xmax=2*pi, tick_formatter=pi, ticks=pi/2, axes_labels=('', '%s'%B)) for B in [-2,-1,-1/2,1/2,1,2]], 3, 2)
