Paint into a target Surface instead of swapping the frame's out

The painters of a pane's body and tag (renderBody and its selection,
gutter, syntax, ANSI and wrap-marker passes; paintPaneTag; paintHeaders;
renderPane; the image and PDF grid paths) take the Surface they paint as a
parameter. The body layer and the tag layers paint straight into their own
temporary surfaces, and the std.mem.swap of p.surface around those calls is
gone. No behaviour change.
