Wez Furlong ba5d50ba9e add window-resized event
This is to support <https://github.com/wez/wezterm/issues/291>.

The window resized event happens asynchronously wrt. processing
a window resize, triggering at the end of the normal window
resize handling.

This commit introduces the notion of whether we are in full screen
mode or not in the underlying event callback, which is useful to
gate the desired feature, which is: when in full screen mode,
increase the padding for the window to center its content.

While poking around at this, I noticed that we weren't passing
the per-window config down to the code that computes the quad
locations for the window.

This commit also changes the font size increase/decrease behavior
so that in full screen mode it doesn't try to resize the window.

```lua
local wezterm = require 'wezterm';

wezterm.on("window-resized", function(window, pane)
  local window_dims = window:get_dimensions();
  local pane_dims = pane:get_dimensions();
  local overrides = window:get_config_overrides() or {}

  if not window_dims.is_full_screen then
    if not overrides.window_padding then
      -- not changing anything
      return;
    end
    overrides.window_padding = nil;
  else
    -- Use only the middle 33%
    local third = math.floor(window_dims.pixel_width / 3)
    local new_padding = {
      left = third,
      right = third,
      top = 0,
      bottom = 0
    };
    if overrides.window_padding and new_padding.left == overrides.window_padding.left then
      -- padding is same, avoid triggering further changes
      return
    end
    overrides.window_padding = new_padding

  end
  window:set_config_overrides(overrides)
end);

return {
}
