textureOffset is defined in the first case. To take away the braces, I'd need to move the definition to before the switch, even though it's only used in the first case. Would that still be preferable?
Perhaps taking away the braces for the cases that don't need them, leaving them for the first case - that way it's less a style decision and more a function decision.

textureOffset is used only once so there is no need to declare a variable.

Also, cases don't need parentheses.

I removed the blocks apart from the first one, but changed the opening brace to be on its own line.
This is more like an explicit block used for restricting scope which is used in other parts of the file.

I'd put this as the first case in the switch, to mirror the enum as well as the UI.
