override fun render(ctx: RenderContext, matrix: Matrix, texture: Texture, texWidth: Int, texHeight: Int, renderColorMul: RGBA, blendMode: BlendMode, filterScale: Double)

The method in charge of rendering the texture transformed using ctx and matrix. The method receives a texture that should be the original image with computeBorder additional pixels on each side.
