Undo for changes happening on a base mesh for multires sculpting.
Use this for multires operators which changes base mesh and which are to be possible. Example of such operators is Apply Base. Usage: static int operator_exec((bContext C, wmOperator op) { ED_sculpt_undo_push_mixed_begin(C, op->type->name); // Modify base mesh. ED_sculpt_undo_push_mixed_end(C, op->type->name); return OPERATOR_FINISHED; } If object is not in sculpt mode or sculpt does not happen on multires then regular ED_undo_push() is used.

Detailed Description

Implements the Sculpt Mode tools.

Usage Guide

The sculpt undo system is a delta-based system. Each undo step stores the difference with the prior one.

To use the sculpt undo system, you must call push_begin inside an operator exec or invoke callback (geometry_begin may be called if you wish to save a non-delta copy of the entire mesh). This will initialize the sculpt undo stack and set up an undo step.

At the end of the operator you should call push_end.

push_begin and geometry_begin both take a wmOperatorType as an argument. There are _ex versions that allow a custom name; try to avoid using them. These can break the redo panel since it requires the undo push to have the same name as the calling operator.

NOTE: Sculpt undo steps are not appended to the global undo stack until the operator finishes. We use BKE_undosys_step_push_init_with_type to build a tentative undo step with is appended later when the operator ends. Operators must have the OPTYPE_UNDO flag set for this to work properly.
