Managed to get portable Linux AppImage binaries to work, so I'm pushing a new release of HDRView! Same as v2.7.0, but with precompiled binaries for Linux.

#OpenEXR best practices
- Real-Time Playback/Compositing: Use B44/B44A or DWA for faster I/O .
- CGI/Rendered Content: ZIP (lossless) or PIZ (smaller files) .
- Texture Maps: ZIP for fast access .
- Layered EXRs: ZIPS for scanline efficiency .
- Avoid Lossy Compression for non-color data (e.g., normals, depth). #exr #vfx #rendering #b3d #CGI

The good news is that it doesn't seem to be very many. I've just found two missing EXR render shots -- of the ones with PNG streams, I mean.

There are also some shots that were still GL previz in the New Years release. That's because there is something fundamentally broken in those files so they don't render correctly or else they crash Blender.

I'm going to work on recovering those next week. I think the plan might be to start a new file and import all the elements into it -- this sometimes works for dicey situations like breakage of backward compatibility and corrupted elements. I've managed to pull meshes into Blender 2.79 from Blender 2.9 or 3.x files this way to redress them with BI shading.
