Screen mirrored

I tried to run the m5stack example on an m5stack core. Using rotation=0 shows the text from right to left. Also width and height are reversed. rotation= 6 shows the text in the upper left corner from left to right, as expected, but width and height are reversed (I set w=320 and h=240, but i need to set w=240 and h=320 to get it right)

Thank you

Glad you got it to work. I have not tried it in an MStack since the rotation stuff was incorporated. I can update the example or happy to accept a Pull Request if you have it working.
