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.
Should be supported for V2 and V3 files. There is code for PVRTCV1 decoding. Can't find any for PVRTC2 (aka PVRTCII)
