// FYI the numbers here don't make much sense out of context
// I am using https://github.com/ThemsAllTook/libstem_gamepad which remaps xinput and dinput states to arrays of button + arrays of axises.
// So those are my tables to read back from them and handle DS4 which provide dinput data.
// The PAD_*** enums are mine, the AXIS_*** enums tells which remapping function to use on the float data.
// You may prefer to handle the axises data in a different manner (e.g. some people like the analog trigger to go -1 to +1, I'm using 0 to 1).
// This is merely a loose reference to get you started if you want to support DS4 in your application.

View Kanji to Kangxi Radical remapping tables
// My game is using a Japanese font that doesn't seem to declare codepoint for Kanjis for those which only comprised of a simple radical.

Some links from twitter on the topic of parsing PSD files (haven't looked into them in details). PSD include a flattened rasterized image so this is easy to load if that's the only thing you need. Most software / librairies have support for extracting this flattened data (e.g. stb_image.h does).

However if you want access to individual layers, render non-rasterized layers, emulate every photoshop features, extract or apply effects with more granularity, more code is needed. May range from easy to lots-of-work depending on what exactly you need.

As far as I know there isn't a trivial stb-like ready-to-use C++ library to do that sort of things. Posting all links here. Some are probably bloated or hard to use into your project, some lacking features.

TODO: Actually look into the pros/cons of all those.

Node graph editor basic demo for ImGui
View imgui_node_graph_test.cpp
// Creating a node graph editor for Dear ImGui
// Quick sample, not production code! This is more of a demo of how to use Dear ImGui to create custom stuff.
// See https://github.com/ocornut/imgui/issues/306 for details
// And more fancy node editors: https://github.com/ocornut/imgui/wiki#Useful-widgets--references
// Changelog
// - v0.04 (2020-03): minor tweaks
// - v0.03 (2018-03): fixed grid offset issue, inverted sign of 'scrolling'
