Minor code improvements from the "low hanging fruit" in initial commit:
- made text start closer to dead centered by changing division constant in the vcm--center-offset function/property - simplified the control of vcm-scroll-offset by removing an unnecessary conditional and making it strictly a variable instead of a property - rearranged order in which the code sections appear - added window-resizing hook, but it is not a complete window-resizing solution because it only works for windows in focus - removed before-change-functions-hook which is made redundant by after-change-functions-hook - added comment clarifications for: - purpose of variable vcm-first-recenter-done - fact that the use of term "properties" in this code is inspired specifically from the definition of properties in Python
- added support for wrapped lines or visual-line-mode
- removed partial resizing support for now until it is more stable - fixed typo in README.md
