(maybe I should have 3 separate posts?)

These are minor things -- maybe just my misunderstanding.

1) Placing the window in the screen Using TBGL_CreateWindowEx doesn't seem to work.
Using the MoveWindow API does work.

2) When using TBGL_RenderMatrix2D,
TBGL_Line uses the coordinates in the TBGL_RenderMatrix2D statement.
TBGL_PrintFont doesn't. Does it use screen coordinates?

3) Are parentheses ever necessary or prohibited? Recommended or not?
e.g. TBGL_UseLighting(%TRUE) or TBGL_UseLighting %TRUE

The script below is commented, showing the issues
Thanks for TB/TBGL!
