Refactored rendering of textures for save and exporting material now saves all textures.
Added an option to start a clear the project, and proper "save" and "save as..." options.
Added support for disconnects.
now load/save dialog use the non-editor classes (thus usable when running the project).
Refactored graphedit and node code (mainly load/save and adding and removing nodes).
Now the material node is aimed at Godot's SpatialMaterial. Textures are generated and passed to the SpatialMaterial (and not generated as shaders anymore).
Rendering textures requires a Timer (to wait for the viewport to be rendered). There has to be a better solution...
Added a couple more examples.
- 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
