Clip Stack

Scissoring can be used to limit rendering to a specific area of the screen. This is implemented by the ClipStack class.

Defining a new scissor area

To add a new scissor window, use ClipStack.addWindow(matrixStack, new Rectangle(fromX, fromY, toX, toY));. This will automatically transform the provided area with matrixStack, as to not break when transforms are applied.

Removing a scissor area

To remove a previously added scissor window, use ClipStack.popWindow();. If you don't want to watch out for possible window remains, use ClipStack.use(matrixStack, rectangle, runnable); instead, which will automatically make a new window specified with matrixStack and rectangle, run your render code in runnable, and pop the previously added window off the stack again.
