Distort filters are unavailable

When you try to use the Pinch, Spherize, Twirl, or ZigZag distort filters on a large image in Adobe Photoshop, they are dimmed (unavailable).

Reduce the pixel dimensions of the image.

There are maximum image pixel dimensions for each of these filters:

ZigZag:    8000 x 8000
Pinch:      11500 x 11500
Spherize:  11500 x 11500
Twirl:       11500 x 11500
