v1.618
NOTE: Version numbers converge to phi. I will likely not bother with semantic releases or anything fancy like that
Add HDR support
- HDR images may be loaded as EXR images
- When HDR images are analyzed, an exposure and tonemapping operator is
needed to convert to LDR ranges - Added support for ACES, Reinhard, and Hable tonemapping operators
- Added exposure slider control (specified in log2 stops)
