Subject: add gesture control for position+width controls of a 2in/2out panner - not used,... 
X-Git-Tag: 3.0-alpha5~873
X-Git-Url: https://main.carlh.net/gitweb/?a=commitdiff_plain;h=41264273ec2a88599263c2506f7b886813472380;p=ardour.git

add gesture control for position+width controls of a 2in/2out panner - not used, since there is no way to create automation for these controls at present
