Description
Graillon diffuse takes 34ms to decode, isn't it a bit much for a 1332 x 1276?
- `JPGD_SUPPORT_FREQ_DOMAIN_UPSAMPLING` adds 7ms by itself

Research direction
Start by profiling the JPEG decode path for the Graillon diffuse image at 1332 x 1276 and compare the reported 34ms with and without JPGD_SUPPORT_FREQ_DOMAIN_UPSAMPLING. The work is done when the source of the decode time is identified and a measured speedup is demonstrated without breaking JPEG loading.
