* `<< text` or `<< int` etc: append to text stream for debugging purposes.
* `setTextColor(COLOR)`: changes default color palette (white).
* `setFontColor(COLOR)`: changes default color palette (white).
* `setFontStyle(const void* data, int size)` if you prefer your own font face.
Changing the font style assumes a tile width of 32 and the same symbol indexes! It also resets the font color and map so call this before doing anything else.
