/*	class SimpleCharMap is a pure 2-dimensional character array with no attributes.
	It is intended to be used as a backing store for FrameBuffer<SimpleCharMap>.

	All character codes incl. 0x00 are available.
	It supports only one foreground and one background color.
	One attribute, e.g. inverted colors, may be achieved by setting bit 7 and using a modified character set:
	--> latin1_256x12[][]  or
	--> ascii_256x12_inverse[][]

	Printing to a SimpleCharMap can be done using `Printer<SimpleCharMap>`.
	.font, .fgcolor and .bgcolor are provided for FrameBuffer<SimpleCharMap>.
