#186 [win 2.4.0] Batch-saved HDR TIFF files (logluv/foat) broken

[Beep6581]

Using the Batch HDR dialog, save HDRs as TIFF files.
Run once with Preferences > HDR Options > LogLuv, and once with Float.
The saved HDR TIFF files are severely clipped (see histogram):

Float: http://i.imgur.com/HpH9rCY.jpg

When HDR TIFF files are created the normal way (not batch), both Float and LogLuv are saved correctly without clipping: http://i.imgur.com/9yqqGGo.jpg
