When a with bg is selected, the cell's regular background will be blended
with 50% opacity selectionBackground in order to retain the bg color info
as well as getting the color to change and getting decent contrast.
This commit also fixes a terrible, nasty bug where the standalone shared
renderer tests were causing the terminal to open multiple times and not
get the WebGL addon activated the second time. So some tests were actually
testing the DOM renderer :o
Fixes#4918
This is a rule I try enforce in PR but it's a bit of a hassle, this will
give a lint warning when it happens resulting in:
- Yellow underline in supported editors when eslint is installed
- Compilation will succeed since it's a warning not an error
- CI will fail as it does not allow lint warnings
Special case comments are ignored which includes @vt comments, table
comments and commented out code.
This removed the allowTransparency code, it didn't actually do much
before, just whether the 'advanced parsing' would allow transparency.
Since we already do the common formats, I'm not even sure what other
format it could be.
