The 1px gap between the vertical ruler and the text widget is rendered by RulerLayout against the parent canvas, which kept its system default background. On dark editor themes this surfaced as a bright vertical strip between the line numbers and the source. Track the StyledText background and apply it to the canvas, so the gap blends into the editor color scheme. Re-syncs on text widget paint events so preference-driven background changes propagate. Fixes eclipse-platform#3964

On dark editor themes a bright 1px vertical strip appears between the line numbers and the source code. The strip is the gap that
RulerLayoutleaves between the vertical ruler and the text widget; it exposes the parentCanvasofSourceViewer, whose background was never themed.This change tracks the
StyledTextbackground and applies it to the canvas so the gap blends into the editor color scheme, and re-syncs on text widget paint events so preference-driven background changes propagate.Fixes #3964
