First version Created base framework and created simple operators

extends "res://addons/procedural_material/node_base.gd"
Improved nodes and added texture export Improved perlin noise and transform nodes. Added an export texture menu entry that exports a texture for the selected node.

Prepared all nodes for caching and added Image node Added Image node that can be used to import textures Renamed all get_shader_code methods to _get_shader code so a caching system can be integrated in node_base (and we can get rid of get_source_rgb and get_source_f functions)

func _get_shader_code(uv):
More nodes and load/save Added basic colorize and blend nodes Started implementing loading and saving texture graphs (most nodes need an update to support this)

var rv = { defs="", code="" }
Updated all nodes and added warp - updated all nodes (load/save support and shader generation) - added warp node

if generated_variants.empty():
Many changes & fixes... - shader updates are delayed by .25 seconds to avouid UI freeze - fixed GraphNode initialization upon loading - started obsoleting get_source_rgb and get_source_f functions - updated colorize node to use gradient - image node can now be loaded/saved - removed iqnoise node - rewrote perlin shader to support a seed parameter (seed is calculated from the node's position, so just move it to reseed) - Added voronoi noise node - updated code to use % formats instead of concatenating strings (should solve type problems in shaders) - reworked the context menu (now has submenus) - fixes in the gradient editor
