Can LCD shift registers keep up with faster MCUs?

If using babystep to adjust the Z probe offset, the axis will move and the mesh will be updated at the same time, causing a doubling of the Z offset over the rest of the print.

To correct for this, the current Z position would need to be modified in the opposite direction, canceling out the additional Z offset added to the mesh. This would be confusing to users, and moreover it would not be accurate without also taking the current Z fade level and current Z height into account.

It might make sense to change the mesh in the case where no babystepping is taking place, but this could be considered an undesirable side-effect of changing the `zprobe_zoffset`.

One way to remedy this would be to return to storing the mesh with `zprobe_zoffset` included, then subtracting `zprobe_zoffset` from the returned Z value. Thus, a babystep moving the Z axis up 1mm would subtract 1 from `zprobe_zoffset` while adding 1 to all mesh Z values.

Without including the `zprobe_zoffset` in the `z_values` there is no safe way to alter the mesh in conjunction with babystepping, although it's fine without it.

LPC1768 VIKI2 & RRDFG are working

looks like all SPIs are working

library change

sh1106 locks up

fixed lockup, started I2C SW com

pretty

re-org

restore a few files

make library happy

switched HAL version of rrd

fix travis error

travis error fixes

another travis fix

cleanup

minor update

one more

correct spacing in platformio.ini

Move 'lcd_bootscreen()' from `lcd_init()` to 'setup()' where it is cexecute exactly once. Saves 'bool show_bootscreen'.
Move the call of 'lcd_custom_bootscreen()' to the begin of 'lcd_bootscreen()'.
Move the delays into the related functions.
Move the picture loop around 'lcd_kill_screen()' into the function.

Addressing #8166

Followup to #8122

add sort alpha section to other LPC1768 boards

* Re-Print of same SD Memory Card file with single click

* Re-Print of same SD Memory Card file with single click
* This is the bugfix-v2.0.0 version of  https://github.com/MarlinFirmware/Marlin/pull/8104

* Add GFX overlay to UBL mesh edit

Fixed misplaced HAS_TEMP_BED in dogm_bitmaps.h

rename _lcd_babystep_zoffset_overlay to _lcd_zoffset_overlay_gfx and move it out of BABYSTEP_ZPROBE_OFFSET to we can use it for over things. Add this function into UBL mesh edit screen.

update all Configuration.h to add ENABLE_MESH_EDIT_GFX_OVERLAY

* Add Sanity to UBL  insanity

Need to check for DOGLCD  otherwise error out.

set_destination_to_current() changed to set_destination_from_current()

set_current_to_destination() changed to set_current_from_destination()
