Some issues related to the padding added to scroll past the end for
console that has padding added.
Added a shortcut to scroll editors one pixel at a time.
Fixed whole lines always drawn at the top even if scroll value is chosen
so that only a portion of the top line is visible. This caused errors in
horizontal scrolling.
Fixed Ctrl-F Ctrl-G and Ctrl-H messing the editor display.
Fixed the end of the line could not be clicked with mouse
Fixed line numbers and their lines could be displayed at different
heights.
Made numbers that represented lines floats instead of integers to allow
partial line display.
