p5 image() friendly error message needs clarification

[ryanachten]

• Found a bug

• Existing feature enhancement

• New feature request

• Image

• Desktop/Laptop

• p5.js version: 0.6.0

• Steps to reproduce this:

Am getting the following friendly error message from p5 concerning arguments passed to the p.image() (with p5 in instance mode).

p5.js says: image() was expecting p5.Image|p5.Element for parameter #0 (zero-based index), received p5.Element instead at webpack-internal:///239:103:9. [http://p5js.org/reference/#p5/image]

Message results from calls such as this: p.image(video, p.mouseX-vWidth/2, p.mouseY-vHeight/2, vWidth, vHeight);.
Video in this case is a p5.MediaElement returned from p.createCapture( p.VIDEO ).

It is unclear as to what is required to resolve the issue since the friendly error message says it was 'expecting a p5.Image or p5.Element' and has 'received p5.Element instead' (p5.MediaElement apparently being a subclass of p5.Element).

(NB: Was referred here from the Processing forum)

i believe this is a dupe of #2576, which was fixed with #2582, but has not yet been released.

can you verify that this is fixed in this build: https://github.com/Spongman/p5.js/releases/tag/untagged-516916da5822156a6263/ ?

@Spongman can verify the friendly error message isn't present when using the unreleased build
