Overhauled window drawing, yet again; fixes issue #155
- Buffer for window content is bigger than the window, minimizes artifacts when window is resized - Back to using XSetWindowBackgroundPixmap() instead of XCopyArea(), no need to handle exposure events; X server can show gray background directly after resize event before sxiv redraws the window contents
