Move win-agnostic parts of draw/drawregion to st.c
Introduces three functions to encapsulate X-specific behavior: * xdrawline: draws a portion of a single line (used by drawregion) * xbegindraw: called to prepare for drawing (will be useful for e.g. Wayland) and returns true if drawing should happen * xfinishdraw: called to finish drawing (used by draw) Signed-off-by: Devin J.
