G26 uses logic that looks like:
```
ex = _GET_MESH_X(i + 1) - (SIZE_OF_INTERSECTION_CIRCLES - (SIZE_OF_CROSSHAIRS));
```
The Bi-Linear macros need parenthesis to work correctly.
These changes may need to be warmed over. I tried to fix things with
the least amount of disruption. I just wanted to get the bugfix_v2.0.0
branch working for people again.
- Fix G26 Circle Drawing.
- Add default extrusion settings so machine can print lines on print bed
- Yet to be done: Get LCD Menu's to use these settings.
* Get UBL Mesh Generation, Mesh Save & Mesh Load working with 32-Bit platforms
* clean up read_data() and write_data() for non-LPC1768 HAL's
* Get read_data() and write_data() return codes consistent
All HAL's read_data() and write_data() return false if they succeed.
* Get read_data() and write_data() return codes to be consistent
Make read_data() and write_data() return true if an error happens.
* Say UBL is now checked out on machine types in default Configuration.h file.
