Create Light and Dark themes

[jscipione]

Haiku should have a light and dark theme. The light theme would come from the current Haiku theme while the dark theme invert the colors so all windows have a dark appearance and all text a light appearance. All apps will need to be updated to use new controls that respect both light and dark themes. BeOS apps will most likely work only using the light theme.

Are there any specifics about why older apps would not work? I don't see why not unless they do things to override the default color scheme.

This might be an R2 thing seeing as BeOS didn't have it. And it would likely require some very thorough forethought on the part of the developers (non of the Linux toolkits I am aware of have a dark theme that doesn't have an issue here or there with readability/visibility)

BeOS apps might work, but mostly will have hard-coded colors which is why I wouldn't think they could be made to work unmodified. This is a big reason that this has to wait for R2.

Any correctly written BeOS app should be using ui_color(), and as such should be able to adapt without much trouble, but there definitely are quite a few that didn't do that, and hardcoded instead.

Dup of #4868.

This isn't a duplicate of #4868, but rather #4868 is a blocker of this ticket.

What is called a "Dark theme" here is a accessibility feature found in some other operating systems for people who have difficulty seeing dark text on light backgrounds.

I know with HaikuThemeManager you already have dark themes.

from #4868 "The result now is that dark themes with bright text is impossible to get right in Haiku."

Usually is "inverted colors" a accessibility feature.

[jscipione]

This is a different feature than #4868 not meant for accessibility just looks
