/** The result should be as follows: We have three times the same image, a billboard with a cube and the text in front.
|
|
They are replicated three times, one centered in the screen without viewport, one in the upper left (qurter screen) and
|
|
one on the right (half screen). The latter is stretched due to the changed aspect ratio.
|
|
The two viewport scenes get the texture drawn over the center as well, using draw2dimage. This should mark the proper
|
|
image position with the top left corner of the texture.
|
|
Finally, each scene has a checkbox drawn at the left side, vertically centered. This will show whether GUI elements adhere
|
|
to viewports as well. */
