class VulkanRendererTest_FlipLeftRightAndRotate90RenderTest_Test

This test actually renders a rectangle using the VKRenderer. We create a single rectangle,

with a half-red, half-green texture (with red first). We translate it and flip the texture on the

left-right axis. The render target is 32x16 and the rectangle is 6x2. So in the end the result

should look like this (note that green is now first):

It then renders the renderable more one more time, rotating it 90* clockwise. This results in the

following image:
