jpeg-x/y-dimension-supported clarifications

Michael Sweet Sep 26, 2025

Based on IPP mailing list discussions, the subject Printer Description attributes could use some clarification:

- The dimensions refer to the JPEG image stream dimensions and not any logical dimensions that can be found in the image metadata.

- X refers to the number of columns and Y to the number of scan lines/rows.
 
- Maybe also mention that X and Y can be different due to hardware codec limitations.
