The scissor bounds check ignores the render area's Y offset

RenderPass.enableScissor throws IllegalArgumentException for scissor rectangles that are fully inside a render area whose Y offset is non-zero.

         if (x >= this.renderArea.x()
            && y >= this.renderArea.y()
            && x + width <= this.renderArea.x() + this.renderArea.width()
            && y + height <= this.renderArea.height()) {

The Y upper bound is compared against the render area's height alone, while the X check on the line above adds the render area's X offset to its width.

Adding the Y offset to that comparison makes both axes agree.
