mtext_lowercase - Lowercase an M-text.
int mtext_lowercase (MText * mt)
Lowercase an M-text. The mtext_lowercase() function destructively converts each character in M-text mt to lowercase. Adjacent characters in mt may affect the case conversion. If the Mlanguage text property is attached to mt, it may also affect the conversion. The length of mt may change. Characters that cannot be converted to lowercase is left unchanged. All the text properties are inherited.
This function returns the length of the updated mt.
