VimState.requestScroll: Scroll by pixels instead of lines, e.g. for inline images

- Problem: scrolling by lines (e.g. ^E/^Y, ^D/^U) with inline images (e.g. using hydrogen or inline-markdown-images) "jumps" over the images as if they're one line, which is very disorienting
- Solution: scroll by pixels instead of lines, calculated from `editor.lineHeightInPixels`
