Sets new size for text in cel.
Err SetTextCelSize (TextCel *tCel, int32 width, int32 height)
Sets a new size for the text cel. If width and/or height are zero, the cel is set to a 1 x 1 pixel size initially, and each time text is placed into the cel the size automatically changes to reflect the size of the characters actually in the cel.
Whenever you change a cel's size, you lose the cel's current contents, because the data buffer is discarded and reallocated at the new size, and after allocation all pixels in the buffer are set to zero.
Non-negative if successful, or negative if a new cel data buffer can't be allocated.
