You should put another parenthese around Image.triangle(x, xx) to tranform it like that

Git tries hard to use accurate syntax descriptions in its manual pages, although it's possible that someone has made a mistake. The [] syntax indicates optional arguments and the parentheses indicate a usage where one of the options is required. This may or may not be how POSIX does it, but in general every Unix system has slightly different standards about how manual pages are to be formatted, so some divergence should be expected. If you feel strongly about changing things, you could propose such a change on the Git list and then send some patches.

It is possible to use git rebase without options or arguments, as jthill pointed out. It may or may not be a useful thing to do in your context. Personally, I prefer to be much more explicit when rebasing with Git and so I don't use that syntax, but that's a personal prefernce; the command can be used that way, even if I choose not to.

Only a subset of UAV formats are supported for loading/storing, which is why the BGRA format fails.

The logic is encoded in this helper function:

A viewport is how much of the window a view takes up. A view is what should be visible in that viewport.

A good scenario of having many viewports would be in a splitscreen game. In a splitscreen game, each player has their own section of the screen. The game can not render one players view inside another players viewport.

Many viewports can also be useful in singleplayer games, like to render a minimap.

Many viewports can also be useful outside of games, like in a text editor. You could have one viewport for the text, and the other for a toolbar.

Think of each window on your computer as being a viewport. You could be in an application that has scrolling, but that is the view moving, not the viewport. When you resize the window, or move the window, you are moving the viewport on your screen - not the view.
