12.0.0 for Minecraft 1.21.2/3

Repository version: 12.0.0+1.21.2

Added

• GuiDescription.get/setUseDefaultRootBackground: can be used to disable the default background painter if your root panel doesn't need it (useful for tab panels)
• Scissors.push overload taking a nullable DrawContext. It's highly recommended that you move existing code to use this overload since it flushes buffered draw calls automatically. Otherwise, parts of widgets etc. can just disappear in GUIs using scissors.

Changed

• Updated to 1.21.2/3
• WDynamicLabel.alignment renamed to horizontalAlignment (along with getters and setters)
