Char_bitmap data: Bitmap data for all characters that are to be defined.
Character bitmap data:
A character is made up of a bitmap the size of which is:
Char. width (X) * Char. Height (Y) bytes.
The bitmap data consists of bitmap patterns for each character in a character set for which the
parameter Char_width in the Char_matrix table is set to a value between 1 and 24. A character
that has its Char_width set to zero, is not included in the bitmap data.
parameter Char_width in the Char_matrix table is set to a value between 1 and 24. A character
that has its Char_width set to zero, is not included in the bitmap data.
The bitmap for one character is then defined according to the following table:
In order to minimize the required storage space, only rows between Ystart and Ystart+Yheight
are included in the character bitmap.
