Gain (slint)

The gain plugin reimplemented with a Slint GUI. Same DSP as the built-in gain example, different frontend.

Source: examples/truce-example-gain-slint/.

#What it demonstrates

• SlintEditor with setup closure and per-frame sync
• Custom .slint markup with Knob, Meter, XYPad from @truce
• Manual callback wiring (on_gain_changed, on_pan_changed)
• Formatted value text synced from Rust (state.format())
• Header bar implemented in .slint markup
• Consistent window sizing between editor and snapshot test
• Screenshot testing with truce_slint::screenshot (software renderer)

#Layout

Header bar with plugin name. Left column with two knobs (Gain, Pan) and an XY pad. Thin stereo meter spanning the full height on the right. All defined in ui/main.slint.
