[FIXED] possible bug output -colorspace RGB is gamma=0.4545

[fmw42]

There is a change in IM between IM 6.8.5.10 and 6.8.6.0 where the output from -colorspace RGB is producing gamma=0.4545 rather than gamma=1.

This is a followup from viewtopic.php?f=3&t=23707



im68510 convert rose: -colorspace RGB -write show: -format "%[gamma]" info:
1

im6860 convert rose: -colorspace RGB -write show: -format "%[gamma]" info:
0.454545

IM 6863
convert rose: -colorspace RGB -write show: -format "%[info:]"
0.454545

IM 6864 beta
imb convert rose: -colorspace RGB -write show: -format "%[gamma]" info:
0.454545


Oddly all these images view darker as if gamma=1. However, all but the first are labeled with gamma=0.4545
