The PixelDisplay class in Mini Micro is a display type that represents a rectangular pixel buffer, with methods to efficiently draw lines, shapes, images, and text.
By default, display 5 is configured as a pixel display, and is in fact the pixel display to which the gfx global refers (unless you change it). But you can make any display layer a pixel display by setting its mode to displayMode.pixel.
A PixelDisplay is 960 x 640 pixels by default (see screen coordinates), though this may be changed via the clear method.
