Web Inspector: Canvas Tab initial user interface needs some polish

• Component: Web Inspector
• Status: RESOLVED FIXED

[BJ Burg]

Grab bag of complaints:

- The "No canvas contexts found" text is vertically misaligned with the similar text in the sidebars.
- The "No canvas context found" text is very thin, and doesn't match the sidebar font weights. I prefer the heavier sidebar weights myself.
- Empty scroll bar track appears when using "Show scroll bars automatically" in macOS System Preferences. It shouldn't be there. I think we have this issue in some other places but this is especially egregious and ugly. For example, Network Tab doesn't have this problem even though it has a scroll container.

This patch will do two things:

1) Add friendlier messages to the empty Canvas Overview screen
2) Consolidate all "message views" throughout the UI to go through WI.createMessageTextView. This will guarantee consistent appearance and reduce code duplication.

Screenshots to follow.

Font size and spacing, as well as text/background colors were chosen to match the page shown in Safari when no network connection is available.

These points should be addressed by the patch.

I haven't taken a look at this yet.

I see similar elements "no-filter-results" in SpreadsheetRulesStyleDetailsPanel. Am I out of date or do those still exist? I guess there was no CSS for that or its not hooked up (I see Devin has a patch to hook up filtering).
