- introducing the notion of: "the text is too small so we do not draw
it" with the help of the function isTextReadable
- removed CanTextGoInTheBox function as it was repeating itself, and
moved it in TGScalableComponent which is way up in the inheritance
- fixed missing initScaling in some diagrams + removed other added
elements such as TextY which is already inherited

- text wont be draw if its size is bigger than the box size and iconSize
- "..." shall be printed if some attribute could not be printed due to
lack of space

- on my way to fix zooms on attributes: just need an element to follow
the last attribute position. If none, need to use the cpt previously
used

Update on fork/join mgt. Not yet finished, must handle more situations and transfer sample number to TML model
