898ed70aa0 Remove <iostream> from math headers. 
This speeds up our build time by using <iosfwd> and un-inlining the
vector print functions.

2ded1c955f cmgen and filament now support RGB_10_11_11_REV 
- RGB_11_11_10 is exported in a RGBA PNG file where the 4 channels are
  used as a uint32 storing a RGB_10_11_11_REV pixel.
  We use the .rgb32f extension, and those PNG files contain garbage 
  when seen in a PNG viewer.

- This is now the default for the -x option.

- compressed KTX files don't encode RGBM, which means they can't
  support HDR, unless an HDR compression scheme is used.

* Properly write HDR files when width < 8 or > 32767

A little oddity in the original Radiance file format encoding.

3f751f3850 cmgen and mipgen should return an error code upon failure. 
These tools can be used in an asset pipeline; build scripts should not
be required to parse stdout in order to determine success.
