32bit Float Density Regression

Describe the bug

Nightly builds result in bpp higher than the uncompressed source. Using 0.10.2 correctly reduces file size.

cjxl metro_noord_2k.hdr.pfm metro.hdr.jxl -d 0
JPEG XL encoder v0.10.2 e148959 [AVX2,SSE2]
Encoding [Modular, lossless, effort: 7]
Compressed to 4144.0 kB (15.808 bpp).
2048 x 1024,  0.200 MP/s [0.20, 0.20], , 1 reps, 16 threads.

cjxl metro_noord_2k.hdr.pfm metro.hdr.jxl -d 0
JPEG XL encoder v0.10.2 60dfa1b [AVX2,SSE2]
Encoding [Modular, lossless, effort: 7]
Compressed to 15722.2 kB (59.976 bpp).
2048 x 1024,  0.548 MP/s [0.55, 0.55], , 1 reps, 16 threads.

To Reproduce

Run cjxl -d 0 metro.hdr.jxl Test.jxl on 0.10.2 and nightly

Environment

• OS: Windows
• CPU type: x86_64
• cjxl/djxl version string: JPEG XL encoder v0.10.2 60dfa1b [AVX2,SSE2]

Thanks for the report. Seems like this was introduced by 27afa5e
Let's see how to fix that...

Perhaps @jonsneyers and @eustas can take a look?

[eustas]

Will take a look soon.

I assume this issue is caused by this: 27afa5e
