Function documentation
static dp_
Creates a dp_
| Parameters | |
|---|---|
| bg | Background to be modified. |
| deltas_ref | Reference to an array of 160 deltas to add to the horizontal position of the affine transformations pivot point of the given background in each screen horizontal line. |
| Returns | The requested dp_ |
The deltas are not copied but referenced, so they should outlive the dp_
