Sets pen number for text rendering.
void SetTextCelPenNumber (TextCel *tCel, int32 penNumber)
Sets the pen number used for subsequent text rendering. The pen number, which must be in the range of 0 through 3, indexes to one of the four possible foreground colors.
When you create a text cel, only pen 0 has a default color assigned; other pens are initialized to no color (transparent). Therefore you must use SetTextCelColors()
and specify nontransparent colors for pens 1-3 before text you render with those pens will appear.
