If the change proves to work as intended, you will essentially have 
three choices:

(A) Use a "#version 3.6" directive and no "assumed_gamma" to get default 
3.6 behaviour.

(B) Use "assumed_gamma" with any #version directive you like (or none at 
all) to get 3.6 "assumed_gamma" behaviour.

(C) Use a "#version 3.7" (or higher) directive and no "assumed_gamma" to 
get the new 3.7 gamma behaviour, which would essentially be the same as 
using "assumed gamma 1.0" plus a ton of improvements for input image files.

(A) and (B) will be for backward compatibility only, and will not play 
well with the new 3.7 gamma-related features such as the File_Gamma INI 
option or the "gamma" SDL keyword. There will also be some caveats 
regarding PNG input files.
