app_server: added more debug output on screen change problems.


# 68667bf4 04-Oct-2009 Michael Lotz <mmlr@mlotz.ch>

* Adding a remote desktop interface that operates on app_server drawing
primitives by providing a RemoteDrawingEngine and a RemoteHWInterface.
Not really optimized yet, still a bit WIP.
* Adding corresponding infrastructure like a blocking ring buffer and network
sender/receiver that are attached to the buffers to feed/drain them as well
as a RemoteMessage helper that provides a message based interface.
* Adding target screen concept to request an app to be run on a specific screen.
It's controlled by the TARGET_SCREEN environment variable which is added on
the app side and sent to the app_server.
* Right now only remote target screens are supported, in which case a new
RemoteHWInterface is created that tries to connect to the given host:port.
* Fix shape bounds when drawing, they need to be translated by the pen position
and converted to screen like the points as well. Wasn't visible though as the
bounds weren't used in the normal DrawingEngine.

# 90ac6655 21-Aug-2009 Axel Dörfler <axeld@pinc-software.de>

* Removed debug output.

# 0eed9183 20-Aug-2009 Axel Dörfler <axeld@pinc-software.de>

* Rewrote screen configuration management: VirtualScreen doesn't have anything
to do with the configurations now, instead, there is a separated
ScreenConfigurations class that maintains all known screen_configurations
per workspace (and the Workspace::Private class has two of them, one for the
current modes, one for the stored modes).
* Added Desktop::{Get|Set}ScreenMode() methods, ServerApp now only calls those.
* Getting and setting of anything else than the current screen is now supported.
* This change also fixes that a temporarily set screen mode was not being
restored on workspace switch.
* Also, the Deskbar now seems to have the wrong location a lot, which is
something that should be easily fixable therefore. I will look into this next.
* Got rid of the unhandy screen_id structure server side, and in BPrivateScreen;
we now just use an int32 - the next API break should definitely replace the
screen_id with a simple typedef.
* Some cleanup.

# 02b6c959 20-Aug-2009 Axel Dörfler <axeld@pinc-software.de>

* VirtualScreen::RestoreConfiguration() now also takes care of collecting the
screens that actually changed their resolution, which simplifies the code
in Desktop considerably.
* Minor cleanup.

fixed BScreen mode.flags handling. This is now compatible with BeOS, and fixes for instance the use of Dualhead Setup for the Matrox and nVidia driver which make use of 'free' flags. A modeset command should be relayed to the accelerant even if it differs by just a single bit: the accelerant best knows how to handle this. Remark: Haiku's screen preflet refuses to set modes once a virtual screen is set since it doesn't recognize the currently set mode. I guess that could be fixed.

# 27c43a2d 08-Dec-2008 Rene Gollent <anevilyak@gmail.com>

Implement the missing pieces to handle per workspace display mode support.
Adjust Workspace view to correctly scale each workspace based on the
resolution of that workspace. This exposes one or two anomalies in other
places in the app_server code though which I wasn't able to track down.
This fixes ticket #693.

# 1938efc0 03-Jun-2008 Axel Dörfler <axeld@pinc-software.de>

* Renamed the "simple" mode setter Screen::SetMode() variant to SetBestMode();
it can also no longer create a default mode.
* This SetBestMode() function now follows a similar logic than the boot loader,
that is, only the width must not deviate, all other values are chosen as
close to the original as possible.
* VirtualScreen::AddScreen() now follows the same logic as the boot loader in
case no configuration was found, and the current screen has no preferred mode
(for example via EDID). That is, it will first try 1024x768, and then 800x600.
* This means there is no mode change anymore when switching from the boot
loader to the app_server in Qemu and VMware.

# 9db35b68 21-Oct-2007 Axel Dörfler <axeld@pinc-software.de>

Revised named configurations a bit:
* Named settings are only overwritten if they were an exact match (ie. it's
the very same monitor).
* The unnamed settings retrieval now has two passes, on the first it will
now ignore named settings. It will also only remove unnamed settings now.
* Added some TODO commments.

# 4ee81443 19-Oct-2007 Axel Dörfler <axeld@pinc-software.de>

* The app_server now stores the whole display_timing structure of a mode, not
just the frequency.
* Previously saved modes are no longer supported, though.
* Screen modes are now stored with the monitor info it belongs to, IOW the
app_server will now choose a mode from the settings that fit your monitor
description. Driver support is required for this to work as intended.
* The changes are completely untested at this point, though, sorry (shouldn't
harm anyone, though) :-)

# 4191a211 12-Oct-2007 Axel Dörfler <axeld@pinc-software.de>

* Started accelerant extension to be able to get the preferred mode from
the accelerant, as well as its EDID info. B_GET_PREFERRED_DISPLAY_MODE and
B_GET_EDID_INFO are both optional. The preferred mode will be taken from the
EDID info if only the latter hook is implemented, or the former returned an
error.
* Currently, the app_server should correctly set the preferred mode on start,
but no accelerant supports that yet, so it's not really tested.

# cb134e25 02-Feb-2007 Axel Dörfler <axeld@pinc-software.de>

Resolved a TODO: WorkspacesLayer must take the whole workspaces frame into account, not
just the one of the first screen. This also solves a locking bug, as the HWInterface
is already read-locked when WorkspacesLayer::Draw() is called.

# 8527f8ff 06-Feb-2006 Axel Dörfler <axeld@pinc-software.de>

The display resolution is now saved and restored. Probably doesn't handle non-default
modes right yet.
The settings are stored in B_USER_SETTINGS_DIRECTORY/system/app_server/workspaces.
They are currently saved as a flattened BMessage - we might want to switch to the
driver_settings format, though.

# 758b1d0e 12-Nov-2005 Ingo Weinhold <ingo_weinhold@gmx.de>

Fixes that make Haiku build with gcc 4. Mainly out of the following
categories:
* Missing includes (like <stdlib.h> and <string.h>).
* Linking against $(TARGET_LIBSTDC++) instead of libstdc++.r4.so.
* Local variables shadowing parameters.
* Default parameters in function definitions (as opposed to function
declarations).
* All C++ stuff (nothrow, map, set, vector, min, max,...) must be imported
explicitly from the std:: namespace now.
* "new (sometype)[...]" must read "new sometype[...]", even if sometype is
something like "const char *".
* __FUNCTION__ is no longer a string literal (but a string expression), i.e.
'printf(__FUNCTION__ ": ...\n")' is invalid code.
* A type cast results in a non-lvalue. E.g. "(char *)buffer += bytes"
is an invalid expression.
* "friend class SomeClass" only works when SomeClass is known before.
Otherwise the an inner class with that name is considered as friend.
gcc 4 is much pickier about scopes.
* gcc 4 is generally stricter with respect to type conversions in C.

# ef8810f2 17-Jul-2005 Axel Dörfler <axeld@pinc-software.de>

Extracted the settings stuff from the Desktop class. If you now need to access
the desktop's settings, you have to do something like this:
DesktopSettings settings(desktop);
settings.SetMouseMode(mode);
The advantage of this is that this object is fully locked, and cannot lead to
corrupted settings anymore. Also, the settings will stay the same until you
delete the object again.
Updated all accesses to use this new API.
Removed no longer used FFM messages.
Implemented AS_{GET|SET}_MENU_INFO for future use.

- removed screen handling from RootLayer
- removed multiple screen/root layer stuff from Desktop, it's
now using a VirtualScreen object instead
