% added const to all static table declarations and updated
code to use const pointers to them. Please remember that
memory regions declared as const can be better optimized
by compiler during compilation and on some machines also
on runtime because can be located in readonly area which
is cached in more efficient way.
! fixed some non const declarations for pure "..." strings

+ added barcode library. It supports these types of barcodes: EAN-13,
EAN-8, UPC-A, UPC-E, Code 128, Code 93, Code 39, Code 11, Codabar,
Interleave 2 of 5 (ITF), MSI.
Library has both C and Harbour level API functions. GC pointers
are used to store Zebra structures in Harbour items.
Current impementation has Cairo draw backend only. Draw A different
backends can be added
Harbour level API:
hb_zebra_create_<type>( cCode [, nFlags ] ) --> hZebra
hb_zebra_destroy( hZebra )
hb_zebra_geterror( hCairo ) --> nError
hb_zebra_getcode( hCairo ) --> cPrintableCode
hb_zebra_draw_cairo( hZebra, hCairo, nX, nY, nLineWidth, nHeight [, nFlags ] ) --> hZebra

+ added test app to generate barcodes. Creates .pdf and .png output,
uses Cairo backend to draw barcode
; TODO: (my todo list with low priority)
- 2-digit and 5-digit supplemental barcodes for EAN13
- draw EAN, UPC barcode in native format
- 2D barcode support
- PDF417
; If someone has real scanner it would be nice to do tests and get feedback.
; I guess I've implemented Code 128 encoding (code set selection, etc) that
generates the optimal (shortest) barcode. If someone can find a sample of
barcode that encodes the same data and is shorter than hbzebra's barcode,
please inform me.
; Make system is not working and a requires to be fixed by someone!
This library has properties that possibly could not be solved in current
make implementation. It can have multiple draw backends: Cairo, Win32 GDI,
GD, ASCII art, libharu, etc. These depends on system and installed
packages. I do not know howto put all backends into the same hbzebra
library. A separate library for each backend seems to be wasteful way to
solve a problem, because draw backend implements only one function (a few
more functions should be implemented to support EAN/UPC native draw, some
2D barcodes, but backend code size is small).
