// SnipHoverButton — NSButton subclass that animates its tint color on hover.
|
||
//
|
||
// Design rationale:
|
||
// - NSButton has no built-in hover state; we install an NSTrackingArea that
|
||
// tracks mouseEntered/mouseExited regardless of focus state.
|
||
// - When the cursor enters, the content tint color animates from `baseColor`
|
||
// to `hoverColor` over 0.2s using NSAnimationContext, matching the spec.
|
||
// When the cursor leaves, the color reverts immediately (no animation).
|
||
// - `baseColor`/`hoverColor` are configurable per-instance so each action
|
||
// button can keep a shared white default but expose its own hover hue
|
||
// (cancel = red, others = blue).

|

// - The overlay window is created with the host screen's AppKit frame and
|
||
// its flipped content view yields top-left local coordinates relative

// to that screen only.
|
||
// - macOS combines all attached displays into a single virtual coordinate
|
||
// space whose origin is the top-left corner of the primary display
|
||
// (Y grows downward). `screencapture -R` interprets its arguments in
|
||
// that space.
|
||
// - Without this translation, a selection on a secondary display is sent
|
||
// as if it were on the primary, so screencapture crops the wrong area.
|
||
//
|
||
// Translation steps:
|
||
// 1. globalX = screenFrame.origin.x + sel.origin.x
|
||
// (NSScreen frame origin.x is already in primary-anchored global X.)
|
||
// 2. globalY = (primaryHeight - (screenFrame.origin.y + screenFrame.size.height)) + sel.origin.y
|
||
// Converts the screen's AppKit bottom-left origin to a top-left global
|
||
// origin, then adds the already-top-left local Y inside the view.
