can you add a note that users will have to reproduce activity in their app to see differences in performance

Added a couple of paragraphs
| reproduce the activity in your app, | ||
| select the new frames in the frames chart, | ||
| to inspect the timeline events | ||
| with the layers disabled. |

maybe add a sentence here that says. "If Paint time or Raster time has significantly decreased, excessive use of the effects you disabled may be contributing to the jank you saw in your app."
@dnfield can you check me here - if a user disables clip layers and sees a performance improvement, where is that improvement likely to show up? In the Paint event on the UI thread? In the raster events?

thanks @dnfield . and is this true for all the layer options here? (clip, opacity, physical shape)

In general, yes - although some build time improvements on the UI thread may be noted, these are things that have more impact on raster time.

(i.e. clipping (especially clipping with anti-aliasing if it is requested), saving layers, drawing shadows)

added a sentence for this in fe1a818
Add a sentence to clarify that raster time is mostly affected when layers are disabled in DevTools
This adds documentation for the "More debugging options" in Devtools.
