We want to have just one base driver that can handle both fullscreen and
windowed mode, so that we can easily switch between modes.
Create a virtual init() method to do construction, so we can move common code
from the derived classes into the base init().
Issue: https://github.com/cebix/macemu/issues/26
On non-Mac platforms, driver_fullscreen constructor sets up software cursor,
but switch_to_current_mode() ask for a hardware cursor, possibly due to a typo.
Neither one ends up being drawn, so the cursor goes invisible.
This change makes them agree to use a software cursor. We should eventually
move to just one place deciding which cursor to use, so they don't have to be
kept in sync.
Fix for bug: SheepShaver compiled with VOSF off will not display
fullscreen on OS X. The VM boots, but the display is entirely black.
This was expected, I suppose, since video_refresh_dga() didn't
actually attempt to draw anything!
The patch fixes this. Notes:
* video_refresh_window() now takes an argument of type driver_base,
since nothing specific to driver_window was used
* video_refresh_dga() can now call video_refresh_window_static()
* update_display_static_bbox() now respects the destination having a
different bytes-per-row from the source
* fullscreen modes are now created for all depths
This fixes the mapping of SDL mouse-button numbers to MacOS/ADB mouse-button numbers,
to correct the reversal of the middle and right buttons. Most useful in conjunction
with a multi-button mouse enabler such as TheMouse2B:

... which can turn a right-click into a control-click.
Software cursor mode is now supported, although currently the existing hardware
cursor mode is used whenever possible. (Software mode will be used if you are
running with a recent version of SDL's Quartz video driver, since a bug in SDL
1.2.11 and later prevents the hardware cursor from working properly with that
driver.)
In hardware cursor mode, the hot-spot is now determined heuristically. Formerly
it could not be determined and was always (1,1), an annoyance for many cursors
other than the arrow.
In hardware cursor mode, the cursor will now be hidden when requested by the
emulated OS (such as when you are typing in a text field).
In hardware cursor mode, some cursor image formats that the code does not handle
correctly will now be rejected, causing the emulated OS to revert temporarily to
software cursor mode. Formerly you would just end up with random garbage for a
cursor. This typically happened for grayscale or color cursors; rejecting images
with rowBytes != 2 eliminates the worst cases.
SheepShaver window a number of times (somewhere around 30 or 40 times will do
it), SheepShaver appears to lock up. This occurs because SDL posts application
activate/deactivate events to its event queue when the mouse moves in/out of the
SheepShaver window, but these events are never consumed, and as a result, the
event queue fills up. Thereafter, no new events can be posted, and user inputs
are ignored. The fix is to consume SDL_ACTIVEEVENT in handle_events().
