EXR, HDR, JXR and PFM formats support High Dynamic Range images (FP values grater than 1).
In summary, here is the list of changes:
EXR, HDR, JXR and PFM: When working with FP formats, the clamp between 0 and 1 is no longer done.
EXR: Removed old SDR code and conversions. Due to the lack of a QImage Gray FP format, Gray images are output as RGB FP (recently added code for Qt 6.8 has been removed).
PFM: Due to the lack of a QImage Gray FP format, Gray images are output as RGB FP.
HDR: Added rotation and exposure support.
With this patch, EXR, JXR, HDR, PFM behave like Qt's TIFF plugin when working with FP images.
