An image and texture viewer for tga, png, apng, exr, dds, pvr, ktx, ktx2, astc, pkm, qoi, gif, hdr, jpg, tif, ico, webp, and bmp files. Uses Dear ImGui, OpenGL, and Tacent. Useful for game devs as it displays information like the presence of an alpha channel and querying specific pixels for their colour.
There is dupe code, especially between E5M9M9M9 and M9M9M9E5. Also look at F11F11F10 and F10F11F11. Add unit tests also.
