.B BadMatch
Some argument or pair of arguments has the correct type and range but fails
to match in some other way required by the request.
.SH NOTES
Unlike XDrawString and XDrawString16,
these functions send no more than 255 characters at a time to the server.
When the total number of characters to be sent is larger than 255,
these functions split the string into chunks up to 255 characters.
After sending each chunk,
these functions query the server to determine the actual text extent.
