the game-type <select>, since IE turns out to ignore display:none on
options. Oh well.
Instead I now do a more transparent thing: when custom game params are
in use, there's a "Custom" option selected in the dropdown, and a
separate 'Re-customise' option which brings the config box back up.
When an ordinary preset is selected, the Custom option is missing, and
there's just a 'Customise'.
In the process I've tinkered a bit to arrange that the custom 'preset'
is always represented by a negative number rather than one past the
last real preset; that seems more consistent overall.

Unlike Firefox, IE and Chrome don't generate keypress events at all if
you suppress the default handling of keydowns. Therefore, we have to
figure out everything from the keydown event, because if we unsuppress
the default handling of any keydowns then we'll get annoyances like ^R
going back to meaning reload-page rather than redo-move.

when the user pressed 'n' for a new game, because all the front end
knows is that it passed a keystroke to the puzzle, and it has no way
of hearing back that a particular keypress resulted in a game id
change.
To fix this, I've renamed midend_request_desc_changes to
midend_request_id_changes and expanded its remit to cover _any_ change
to the game ids. So now that callback in the Emscripten front end is
the only place from which update_permalinks is called (apart from
initialising them at setup time), and that should handle everything.

mention that the HTML pages generated by html/jspage.pl are also an
integral part of this front end. (The NestedVM frontend is more
self-contained, needing only an appropriate <applet> tag, but this one
expects quite a few components to exist on the page and have the right
ids.)

The previous version dealt adequately with rectangles _partially_
overlapping the edge of the canvas, but doesn't correctly handle a
rectangle that's completely out of bounds in one direction. Replace
with a complete rewrite which is more easily seen to be correct. Also,
while I'm at it, add a missing condition to draw_update() so that we
don't even bother calling the Javascript half of it on any rectangle
that's been trimmed into nonexistence.

selected. Previously we were leaving the first element on the list
selected, which is _usually_ right, but not right for Slant.
In the process of doing this, I've also reorganised to fix a crash
which shows up with non-configurable games (admittedly currently only
Nullgame :-) when we still try to call js_select_preset in spite of
not having any preset options to select.

can trigger a call to a front end notification function. Use this to
update the game ID permalink when Mines supersedes its game ID.

type dropdown, we still get an 'onchange' event if they select it a
second time. Normally this wouldn't happen, because onchange means
what it says and we only get it if a _different_ element is selected.
My solution is to create two list items called Custom, set one of them
as display:none to stop it showing up when the list is dropped down,
and to select it after the configuration box closes.

applets, here's an alternative webification in Javascript, using
Emscripten in asm.js mode (so that as browsers incorporate asm.js
optimisation, the game generation should run really fast).
