[Reference] saveFrame

[maxdevjs]

Issue description

A processing.org/reference/saveFrame_.html statement seems incorrect:

// Saves each frame as screen-0001.tif, screen-0002.tif, etc.
saveFrame(); 

URL(s) of affected page(s)

processing.org/reference/saveFrame_.html

Proposed fix

Update processing/processing-website/content/references/examples/processing/saveFrame_/saveFrame_0.pde

from

// Saves each frame as screen-0001.tif, screen-0002.tif, etc.
saveFrame(); 

to

// Saves each frame as screen-0001.tif, screen-0002.tif, etc.
saveFrame("screen-####.png");
