Features:

--Add support for Exr files which use 32-bit floats for each RGBA channel. Seems to come out too washed out.
--Allow for clearing an individual color curve.
--Allow for saving multiple image types in EmberRender and EmberAnimate. All writes are threaded.
--Remove --bpc command line argument. Add format png16 as a replacement.
--Remove --enable_jpg_comments and --enable_png_comments command line arguments, and replace them with --enable_comments which applies to jpg, png and exr.
--Add menu items to variations and affine spinners which allow for easy entry of specific numeric values like pi.
--Make final render dialog be wider rather than so tall.

Bug fixes:
--Fix some OpenCL compile errors on Mac.
--Remove ability to save bitmap files on all platforms but Windows.

Code changes:
--New dependency on OpenEXR.
--Allow Curves class to interact with objects of a different template type.
--Make m_Curves member of Ember always use float as template type.
--Set the length of the curves array to always be 2^17 which should offer enough precision with new 32-bit float pixel types.
--Set pixel types to always be 32-bit float. This results in a major reduction of code in the final accumulation part of Renderer.h/cpp.
--Remove corresponding code from RendererCL and FinalAccumOpenCLKernelCreator.
--Remove Transparency, NumChannels and BytesPerPixel setters from Renderer.h/cpp.
--Add new global functions to format final image buffers and place all alpha calculation and scaling code in them.
--Blending is no longer needed in OpenGLWidget because of the new pixel type.
--Make new class, AffineDoubleSpinBox.
--Attempt to make file save dialog code work the same on all OSes.
--Remove some unused functions.
