#1 scale text with rotation

[Miguel Angelo Couto Castro]

There is a bug in the way the scale of text is done.

The scale factor is currently being retrived from the [0][0]
position of the transform matrix. But when we apply a rotation to
the matrix that position no long olds a good value to use as a
scale factor.

the method that uses that value is the float getScale() at
Scene.java

another way solve the problem is sending a extra point at the
end of the points array.

any other ideas are welcome!

dont forget that performance is the main goal!
