Add a 普通窗口模式 switch to the general settings section. When enabled the
window is created with WS_EX_APPWINDOW instead of WS_EX_TOOLWINDOW, so it
appears in the taskbar and Alt+Tab, and losing focus no longer hides it. The
extended style switches live without a restart; a failed save rolls the
checkbox back and reports the error, and the general section now reports
save failures instead of discarding them.
The switch is drawn anti-aliased. GDI's RoundRect has no smoothing, and at
22 logical pixels tall the staircase on the pill and the knob read as a
low-resolution control, so both shapes are rasterized together at 4x and
halftone-downscaled. The off track uses p.faint: p.line is the card border
and p.pill is the card fill, so the previous colours made the switch
disappear into the card it sits on.
