SCEnvelopeEdit is a vector-based breakpoint editor for the Env class. It takes an Env object as an argument that is modified from the GUI. Changing properties of the Env object directly will not be reflected on the GUI. You must call 'refresh' after doing this. You cannot add breakpoints.\
\
The breakpoints are color coded as follows:\
blue - normal\
red - sustain node\
green - loop node

\
refresh()\
\f1\b0 If the Env object is modified directly, this needs to be called to update the GUI.\

\f0\b \cf0 minLevel_(float)
\f1\b0 \
Changes minimum level shown in editor.
\f0\b \
\
maxLevel_(float)
\f1\b0 \
Changes maximum level shown in editor.\
\
\f0\b minTime_(float)
\f1\b0 \
Changes minimum time (sec) shown in editor. Negative times are okay because Env uses inter-node \
durations.\
\
\f0\b maxTime_(float)
\f1\b0 \
Changes maximum time (sec) shown in editor.
