Dev:Source/Modifiers/Stack/API Refactor

Overview

This page describes work to refactor the modifier stack API. The current aim is to split modifier.c into one source file per modifier, leaving only the stack management functions in modifier.c. This should make the system easier to understand, and facilitate work on individual modifiers.

Directory structure

The new directory structure is inspired by the nodes API.

• A modifiers directory has been added, which holds all the code for specific modifiers
• modifier.c is still in the blenkernel/intern directory, but now it only holds modifier stack API functions
