A library to easily use grayscale on the Thumby
In the current version the ghost blocks are drawn over the falling piece. This PR puts them beneath.

I got a thumby a couple weeks ago and when using the grayscale library, the image either flickers between two positions, or is just monochrome. It gives different results randomly,...
Starting the BrightnessTest, at least in Fast Execute (menu launch not tested) will have a bright horizontal artifact roll down the screen and then become stable.
For that device, 0 is off and 1 is lowest brightness. Thanks to Unimatrix0 for sharing fix: "... the low brightness being broken can be fixed by simply changing brightnessVals=[0,28,127]...
thumbyGraphics: ``` def drawSprite(self, s): self.blit(s.bitmap, int(s.x), int(s.y), s.width, s.height, s.key, s.mirrorX, s.mirrorY) ``` thumbyGrayscale: ``` @micropython.native def drawSprite(self, s): self.blit(s.bitmap, s.x, s.y, s.width, s.height, s.key, s.mirrorX, s.mirrorY) ``` Thanks...
