[B2-devel] [PATCH] SheepShaver fullscreen on OS X

[Dave V. <va...@us...>]

Hi folks,

Thanks for all your work on Basilisk II and SheepShaver, they're truly
amazing programs! However, there's a little bug: Current SheepShaver
SVN compiled with VOSF off will not display fullscreen on OS X. The VM
boots, but the display is entirely black. This is expected, I suppose,
since video_refresh_dga() doesn't actually attempt to draw anything!

The patch at http://vasi.dyndns.org:3128/files/patch/sheepshaver-fullscreen-3.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

I have two relevant questions:
* Why was non-VOSF SheepShaver previously restricted to just one depth
when using fullscreen? Seems to work fine with all depths.
* Why is update_display_static() used only for depths < 8 bits?

Comments welcome.
