Add toilet POI icon for marking bathrooms/restrooms/toilets

[Pengor]

Adds a POI for toilets 🚽 I just realized this POI was missing so I thought I'd take a swing at it:

I figured the infrastructure color made the most sense, but I'm certainly open to changing that. I first attempted a side-view of a toilet as the icon and then a 45° angle view (semi-3D) but neither turned out very well in my opinion.

At a glance, the front view looks to me more like ⚱️ or maybe a fancy chalice. A toilet wouldn’t have been my first guess. Would a top-down view, heavily simplified, be more recognizable?

The classic pants/dress iconology is referenced in US government standards and is by far the most recognizable symbol for a bathroom.

This is the AIGA symbol. It is certainly recognizable, although it’s optimized for a conventional configuration of men on one side and women on the other. These days it’s a bit simplistic. There’s nothing wrong with POI icons leaning into abstractions, but then we might as well go for metonymy, such as a toilet or toilet paper roll. This is not unlike how #1014 eschewed the classic library icon in favor of a book.

More particular to this project, the AIGA symbol has the potential to mislead the user about what’s actually under the icon. All we get from the tiles is the location of an amenity=toilets, whether it’s just one POI for the whole facility or one POI per room.

(As a side note, the AIGA symbol is not as universal as one might imagine. The standard, legally required signs in California are a triangle and a circle. Both of these symbols are heavily overloaded, including for rest areas: #443.)

I think the side view of a toilet is an improvement over the front view; much more recognizable. Just a couple more things:

Toilets in diagrams are more likely to face right in the United States. Can't say why, but it just feels like it fits in better with left-to-right text.

The base of the toilet is too narrow—it looks as if the toilet seat is teetering on a small flower pot. The silhouette of the National Park Service standard icon has a decent base with more mass, that might serve as inspiration.

I'm fine swapping this if we want to do so. For the sake of comparison against previous icon attempts, let's save that decision until the end though.

The effect (specifically at the scale the icon gets displayed at) is pretty minor, in my opinion, but here is an attempt at more of an hourglass-shaped pedestal:

I also tried swapping the colors (resulting in a mostly white icon):
