Better scaling and translation of 3D text, within viewport.

Not rendering scrolly text if it's outside of boundaries.

Finer control of where scrolly text appears.

Defining leftTextRenderX, leftTextRenderY, rightTextRenderX, and
rightTextRenderY to make things clearer.

Adding a comment.

Adjusting translation of block after rotation if it causes the block to hit the
well walls; mimic SimpleGameLogic.

Changing over from using BlockGenerator.chooseRandomCompositeRotation(), to now
using BlockGenerator.getPreferredCanonicalRotation(). The computer player is
making very quick and accurate moves now. Looks dandy.

Now using BlockGenerator.chooseRandomCompositeRotation() for choosing a random
composite rotation from a list.

Adding some new public methods that are related to choosing a canonical
rotation.

Changing width of popup window to be more suitable.
