void UnloadFont(FontDescriptor * fDesc)
LoadFont() or ParseFont() processing. If the font was loaded via LoadFont(), releases the FontDescriptor and unloads the file image, releasing the memory it occupied. If you loaded the font file image yourself and called ParseFont(), UnloadFont() releases the FontDescriptor. In that case, you must unload/release the font file image yourself.
Because TextCel structures contain a reference to a FontDescriptor, you must delete all TextCels that reference a FontDescriptor before you call UnloadFont() for that descriptor.
