It looks like TIFF_SETGET_C0_DOUBLE has no case in the switch in tif_dirread.c
I would have liked to use it to support TIFFTAG_GPSIFD reading/writing through a custom TIFFFieldArray, where several tags expect a fixed number of 3 rationals, i.e. degrees, minutes, seconds.
I could of course go back to TIFF_SETGET_C0_FLOAT in my custom TIFFField array, which may be sufficiently precise for almost any use case. Or I could use TIFF_SETGET_C16_DOUBLE, which it looks like has its case in the switch statement...
However the entire recently included exifFields array in tif_dirinfo.c uses double for the rational fields defined in EXIF, so may I ask if the omission of TIFF_SETGET_C0_DOUBLE is intentional or just because no one realized it's missing?
