The routine gSetCharTransformMode() switches the transforming of characters on and off. The call to gSetCharTransformMode() takes effect when characters are subsequently output provided there has been no intervening call to gSetHardCharSize().
When the transforming of characters is switched on, all characters are generated by GINO to exactly the size, orientation and italic angle requested. They are also drawn subject to the current transformation, clipping/masking limits and line style (ie. according to the current line width, broken line style and line end type).
If gSetCharTransformMode(GOFF) is called, the current character mode reverts to the character mode set by the last call to gSetHardChars(), gSetMixedChars() (default) or gSetSoftChars().
