Polygrid sorting

[Paul Dupuis]

Okay, I built the stack and tested it under Windows 10. The 3 beeps are 
intentional. It is to let me know when it is done as some test with 500+ 
columns/rows takes a while. It does display under LC9.6.8 (64 bit) on 
Windows 10.

Now I have to go try it on macOS?

There is data in the pgcolumnnames and pgdata custom properties (so those values were defined). It’s just the grid that did not appear. Thinking it might be my laptop (apple silicon M1) I tried it on an Intel MacBook Pro and got the same result.

The columns headers are text and the left most column ROWs are test and all other cells are numbers. Some customers can have quite large data sets and I have been running into the number of columns (ad a default width of 100px per column) exceeding a GROUPs 32,767px width maximum (about 327-328 columns). At this point the Datagrid just fails - no data is displayed.

See https://quality.livecode.com/show_bug.cgi?id=23880. If you might benefit from this enhancement, please follow the bug or add a comment to that effect.
