Hard coded gamma value (massive bug)

Gamma is hard coded to 2.2 (which destroys all rendering with alpha values and any kind of blurring)

synfig.org/issues/thebuggeni … issues/150
synfig.org/issues/thebuggeni … /issues/17

and several other reports… (some saying the bug has been fixed–when it doesn’t seem to have been)
Ive tried both synfig studio and command line versions of: synfig 1.0.2
Both fail.

This has been open for 3 years–and it makes synfig unusable for me and probably many others.
Is this easy to fix? Its not a case of changing a variable?
