Don't know when it was added or how well-known it is. (Or how useful it is)


Unfortunately not very useful as I touched on in the last paragraph of the original post. It's become quite popular for games ...

TL;DR
Improve object/state readability by making their shapes more unique, in addition to their colors.


What ?
A great example of colorblind-friendly design is road signage. They don't rely on color, but use it as enhancement. Think of how a stop sign can even be recognized when fully covered ...

Thanks! I'll try that. It would be great for it to be supported again at some point.

That is very unfortunate. I do not see how tiling should interfere with this, but kinks in the graphics pipeline can always lead to weird bugs. I hope this gets resolved someday. Those artifacts drive me nuts.

I would like to suggest texture subsampling (and possibly mip-mapping) for rendering. It would greatly improve how well bitmaps appear during scaling and translation. This would get rid of all non-integer scaling artifacts like flickering or jitter (especially noticeable when looking at Transport ...
