	0x0C\|Height (pixels) \|4 bytes little endian		0x0C\|Height (pixels) \|4 bytes little endian

			* ''Bitmap data offset'' is the offset relative to the end of the character info table.

			* ''Logical width'' is the amount of space between the X coordinate and the next character, when drawing, as opposed to the ''Width'' field, which is the physical width, of the character's bitmap and it is only used to load the bitmap data itself.

			* ''Vertical offset'' is used to determine where exactly the character should appear vertically, relative to the Y coordinate, and it is usually the negative of the character's physical height.
