Screenshot created in 'perspective' projection mode is darker than expected

See original GitHub issue

Description: Using A-Frame’s built-in keyboard activated screenshot the output of perspective screenshots is darker than expected. It is also darker than equirectangular screenshots from the same scene.

To reproduce:

Go to https://kfarr.github.io/3dstreet/#https://streetmix.net/kfarr/3
Press ctrl + alt + s
Press ctrl + alt + shift + s
Compare the resulting output

Suggested fix:

Note that equirectangular projection uses sRGBEncoding encoding (link)
I think you can insert encoding: THREE.sRGBEncoding, before line 93

Normal ticket questions:

A-Frame Version: 1.1.0
Platform / Device: Mac OS Chrome Desktop
Reproducible Code Snippet or URL: See above

In Version 1.3.0 I get this bug too. In the following pictures there is a clear color difference. I’m not sure if it may be the same problem.
