|Subject: [PATCH] [vbell2] add visual bell with two rendering modes
|
|- Inverse the whole terminal - "standard" visual-bell, a bit jarring.
|- Inverse outer (border) cells - much less jarring, yet plenty visible.
|
|Note: blink used a timeout of 1us after drawing, probably to
|re-calculate the timeout without being affected by draw speed. This was
|changed to 1ms for code simplicity, and should be inconsequential.
