Fog of war =
1) Divide world into tiles.
2) Tile can have any of 3 states { FOGGED, PARTIALLY FOGGED, CLEAR }
3) If tile = FOGGED, draw black (or don't draw at all if you're
clearing to black)
4) If tile = CLEAR, draw normal stuff.
5) If tile = PARTIALLY FOGGED, draw normal stuff, determine which
direction the blend is in (examine surrounding tiles) and draw a pre-
made tile of partially blended fog at the orientation you determined
it to be in.
As far as drawing or not drawing characters under fog of war, just
examine the tile they are currently standing on to figure out whether
or not to draw them.
It's actually not that hard to implement in Canvas or OpenGL if you
plan ahead a little and tile your world.
The one thing you do not want to do is draw everything and then try to
draw the fog on top. That's way more pixel writes than optimal and
will probably give subpar performance on many devices.
