Bug fixes
- Windows file I/O performance bug fixed. In some cases, reading a image
  near the end of the file was very time-consuming (though correct data
  was returned). Detailed explanation: jump to an image in the last buffer
  and start reading there. This caused a ReadFile of the next buffer, which
  happens to be located _after_ the end of the file. This "read ahead"
  operation returned an eof flag, which was (erroneously) ignored. Hence,
  every successive fread() operation caused this ReadFile attempt on the
  file system, resulting in a huge overhead. In cpfspd, every video line
  is read using a fread(). This is solved by taking the eof flag into
  account when starting the "read ahead" ReadFile operation.

Functionality
- Convenience functions for HDR (float <> f16 conversions) made available
  to end user

Miscellaneous
