Linear output forced on every scene

Component:Blender Exporter
Category:bug report
Assigned:David Bluecame

YafaRay linear output (gamma output=1) is forced on every scene, even on scenes coming from older versions of Blender which may not have Blender sRGB color management by default enabled when opened with new versions of Blender. Gamma output = 1 only makes senses if Blender sRGB color space is enabled, but I suspect many people end using YafaRay linear output with Blender sRGB color space disabled.

First, I believe that should be a check system so scenes from older versions of Blender which have sRGB color space disabled once opened with Blender new versions, should have it's original gamma output (2.2 or whatever) unchanged.

In general the yafaray gamma output value should be linked to Blender color pipeline status and viceversa so if Blender sRGB space is disabled then used defined YafaRay gamma output is used with 2.2 as default. Also maybe we should give gamma output a more explicit value like user defined or Blender color space.

I've sent a pull request with a change, so the user can see warning messages in the Render settings panel if Alpha=1.0 and Scene display device is set to "None".

In the same pull request I've changed the default value of the Input Gamma to 2.2 in all operating systems.

Gamma settings changes and warning if Alpha=1.0 and output device=None
