[Bf-committers] Colormangement is painfull

[Tobias Oelgarte]

In the recent days I stumbled upon multiple bugs in relation with the 
colormangement.

The first thing is the use of colormanagement inside the Image-Editor, 
which is automatically enabled as soon you load an image with 
float-values (32-bit), even so the image itself is intended to be 
linear. Additionally the performance inside this mode is horrible. 
(#28193,

)

The second thing is the texture node inside the material nodes. It 
always uses colormangement and gives different results as if inside 
material-slots. (#28235, 
http://projects.blender.org/tracker/index.php?func=detail&aid=28235&group_id=9&atid=498 
)

That leaves me the question why colormangement is done to textures at 
all? So far I could not see any realistic use-case inside this components.

At least someone should tell me how i could get colors from linear -> 
managed and managed -> linear to workaround this issues.
