// 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.

// Mapping for PlayStation 4 DualShock 4 (PS4, DS4) controller exposed via DInput.

// 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.
// e.g. https://en.wikipedia.org/wiki/Radical_180
// Radical 180 (U+2FB3) ~~ 音 (U+97F3)
// I am remapping the codepoints in software but couldn't find an easy to parse list, ended up scraping from Unicode webpages

  { 0x4E00, 0x2F00 }, // Kangxi Radical One
	{ 0x4E28, 0x2F01 }, // Kangxi Radical Line
	{ 0x4E36, 0x2F02 }, // Kangxi Radical Dot
	{ 0x4E3F, 0x2F03 }, // Kangxi Radical Slash
	{ 0x4E59, 0x2F04 }, // Kangxi Radical Second

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.
