Thank you @Nprod.

and some more comments

in dogm_lcd_implementation.h
by using standard font and
shifting down temperature displays by one pixel
Saves 2300 bytes.

- Compare pr_char to space
- Fewer calls to lcd_strlen

- Get rid of _selected functions, passing selected state instead

- Addressing issue #1608

Warning: suggest parentheses around comparison in operand of &

pretty much helped.

- Add support for 4th extruder
- Fix parentheses matching
- Apply coding standards
- Address issue mentioned at #1575

- Add BIT and TEST macros
- Add _APPLY_ macros to stepper.cpp to help with consolidation
- Consolidate code in stepper.cpp using macros
- Apply standards in stepper.cpp
- Use >= 0 instead of > -1 as a better semantic
- Replace DUAL_Y_CARRIAGE with Y_DUAL_STEPPER_DRIVERS

Cleaned typo in language_test.h Cyrillic part.

- Make separate get_pid_output(e) and get_pid_output_bed() function
- Reduce size of manage_heater function
- Hopefully work around linker errors

Automatic selection was to unflexible.

Updated documentation

Updated language files to new logic and documentation.

Updated bdf2u8g.exe

- Fix for #1591 replacing #1595

short:
this script scans the first few lines from a gcode. If the line between 2 different z are greater than min_g1 this is our first layer. On this layer we search the min and max values of X and Y. With an offset we write that in a new file.

Improve description in Configuration.h

The max acceleration limiting was in wrong place.

Added option to set Travel Acceleration (non printing moves).
The M204 options was a non sense (S for printing moves and T for retract
moves).

It has been changed to:
P = Printing moves
R = Retract only (no X, Y, Z) moves
T = Travel (non
printing) moves

I will add this info o G-Code wiki in reprap.org. I also advise to put
this info in Marlin next version changelog.

I forgot to enclousure the variable with #ifdef

Top -> down
- Decide what output function is to use.
- Precautions. If non of the DISPLAY_CHARSET_HD44780's is selected fall back to Japanese.
- When we are not on the dogms setup a mapping table depending on display type and mapper.
- If we are on dogm we use ONE To ONE mapping - except kanji.
- select and define one of the mapping functions.

And made falback to kana work.

Top -> down
- We don't need the old Marlion_font package any more - we made new.
- But we need information about configured fonts and the mappers.
- We support Cyrillic now.
- LCD_CLASS is not used in this file. LiquidCrystalRus.h is deleted anyway.
- define some fonts
- BIG_EDIT_FONT works only together with western languages.
- Select a matching FONT for the MENUE depending on the defined language.
- Number the different font-types. Wanted to avoid to store complete font-structures when changing fonts back and forth.
- Marlin special symbols are now at the lower end - like in 'ultralcd_implementation_hitachi_HD44780.h'
- insert the new remembering setFont function.
- insert the new counting lcd_print functions.
- make use of the new setFont and lcd_print functions.
- On some places redefined one character long strings with chars to avoid overhead and reduce warnings.
