Description

Description of the new feature/enhancement

Invisible text is generally rendered as text with a foreground color equal to the background color. This can be repro'd as a part of https://github.com/jdebp/terminal-tests/tree/master/PowerShell).

This makes it not look invisible, however, because we apply the acrylic texture to the background, but not the foreground.

Proposed technical implementation details (optional)

Just make the renderer not render the invisible text. Ignore it completely.

Contributor guide

Research direction
Identify where the renderer draws text and add a check to skip rendering when text is concealed (foreground color equals background color).
