2004-06-11  Al Riddoch  <alriddoch@zepler.org>

	* src/Render.h, renderers/GL.h, renderers/GL.cpp,
	  common/Utility.h, common/Utility.cpp:
	  Change some pass by value arguments to pass by reference
	  for efficiency.

2004-06-10  Al Riddoch  <alriddoch@zepler.org>

	* src/WorldEntity.h, src/WorldEntity.cpp,
	  src/Frustum.h, src/Frustum.cpp,
	  src/Character.h, src/Character.cpp:
	  Change some pass by value arguments to pass by reference
	  for efficiency.

	* gui/Workspace.cpp: Get rid of some annoying debug ouput.

2004-06-09  James Turner  <james@worldforge.org>

	* Updated method for computing the fog color, based on the current
	  horizon color. Rather than using readPixels, which is slow,
	  sometimes drastically so, store the first (bottom) row of
	  the atmosphere texture in client memory, and do our own
	  interpolation.

2004-06-09  Al Riddoch  <alriddoch@zepler.org>

	* gui/Workspace.cpp: Start writing event processing code.

2004-06-09  Al Riddoch  <alriddoch@zepler.org>

	* renderers/GL.cpp: Enable character light source, and provide

	* renderers/GL.cpp: Remove pointless call to glClear.

	* environment/SkyDome.cpp: Clear screen after reading back fog
	  colour which eliminates flickering sky, and makes stars twinkle.

2004-06-07  James Turner  <james@worldforge.org>

	* Fix linux compilation of stars code. Thank goodness
	  I have a Loonix box these days.

2004-06-07  James Turner  <james@worldforge.org>

	* Add star rendering to the environment code. Very simple while the
	  renderer integration issues are sorted out; in the future, will use
	  point sprites and colors. 
	  
	* Add a stars state to states.cfg
	
	* Add an unsigned 8-bit RGBA color to common/types.h
	
	* Add a long 'skirt' to the sky dome, and hence always use pure
	  black as the glClear color. We still need the glReadPixel hack for
	  getting the fog color, will address that in a future change.

2004-06-07  Al Riddoch  <alriddoch@zepler.org>

	* gui/Workspace.cpp, gui/Workspace.h, src/System.cpp: Pass
	  SDL events to the gui code.

	  and add methods to allow widgets to install stuff.

	* src/System.cpp: Test out new Toplevel.

2004-06-03  Al Riddoch  <alriddoch@zepler.org>

	* gui/Button.cpp, gui/Button.h, gui/Container.cpp, gui/Container.h,
	  gui/Graphic.h, gui/Label.cpp, gui/Label.h, gui/Widget.h,
	  gui/Workspace.cpp, gui/Workspace.h: Add show interface to widgets
	  for when they are ready to be rendered.

	* gui/Toplevel.h, gui/Toplevel.cpp: Class for top level widgets.

2004-06-03  James Turner  <james@worldforge.org>

	* XCode project updates - want to be able to revert to this
	  version if I break stuff.

2004-06-03  Al Riddoch  <alriddoch@zepler.org>

	* gui/Window.h, gui/Window.cpp: Add coords and size, adding children,
	  and the render interface which allows us to render windows
	  as a hierarchy.

	* gui/RootWindow.h, gui/RootWindow.cpp: Implement render to
	  iterate over children.

	* gui/Frame.h, gui/Frame.cpp: Fix render interface to comply with
	  base class, and draw based on window coords.

	* gui/Container.h, gui/Container.cpp: Remove render interface, as
	  this widget type is not rendered. Implement constructor and
	  destructor.

	* gui/Workspace.h, gui/Workspace.cpp: Make workspace
	  a container, so it can hold top level widgets. Implement
	  rendering the rootwindow when draw is called. Add a demo
	  widget.

2004-06-02  Al Riddoch  <alriddoch@zepler.org>

	* gui/Workspace.cpp: Fix test gui drawing code, and make it use
	  vertex arrays. Add necessary states entry.

2004-05-30  Al Riddoch  <alriddoch@zepler.org>

	* renderers/TextureManager.cpp: Fix texture load error detection,
	  and make output a little more useful.

	* renderers/ImageUtils.h: Add newline to end of file.

2004-05-30  James Turner  <james@worldforge.org>

	* Change an assert() on texture load errors to something less
	  violent, just print an error and stop generating mip-maps.

2004-05-30  James Turner  <james@worldforge.org>

	* Refactor texture ID generation, to avoid manual resizing of the
	  STL containers (they behave smartly anyway). As a result, got
	  rid of m_texture_counter completely (use m_names.size() instead)
	  
	* Added a general config option, base_texture_level, and a console
	  command, /set_texture_detail, to allow playing with texture
	  detail at runtime.
	  
	* Cleaned up the TextureManager's interactions (or lack of) with 
	  the config system.
	  
	* Factored the image load code into a helper file, ImageUtils.cpp
	
	* Rewrote the mip-mapping to never use SGIS_GENERATE_MIPMAPS,
	  since it is hard to integrate with dynamic texture detail reduction.
	  This also allows us to use arbitrary texture storage formats in
	  the future, since the only call we make to load textures is
	  glTexImage2D diurectly.
	  
	* Added custom mip-mapping code to ImageUtils.cpp : not the nicest
	  code ever, but pretty simple and it seems to work.

	* Found a latent bug in the texture loader, where 8-bit (single channel)
	  surfaces were being treated as 32-bit. I have default these to
	  GL_ALPHA for the moment, but perhaps they should default to
	  GL_LUMINANCE? Need to ask Al and Simon.
	  
	* Removed the include of SDL_image.h from System.h, since only two
	  source files (System.cpp and ImageUtils.cpp) ever call SDL_image
	  functions.

2004-05-28  Al Riddoch  <alriddoch@zepler.org>

	* gui/Workspace.h, gui/Workspace.cpp: Hold reference to system object
	  in gui, for access to renderer etc. Add text rendering code.

	* gui/Widget.h: Remove rendundant render() interface.

	* src/System.h, src/System.cpp, src/Graphics.cpp: Add a gui Workspace
	  into the render loop.

2004-05-28  James Turner  <james@worldforge.org>

	* Refactor texture config code, so we default to using
	  mipmaps. Ensure we use findItem before calling getItem.
	* When mipmapping is enabled for a texture, make the
	  default MIN_FILTER be GL_LINEAR_MIPMAP_LINEAR
	* Add in inital (hard-coded) logic to use a different
	  base mipmap level.

2004-05-26  James Turner  <james@worldforge.org>

        * Remove <strstream> check from configure, and usage from
          Utility.h

	  renderers/default_font.h: Use pure alpha texture for font,
	  and enable blending and get smoother less aliased text.

2004-05-24  Al Riddoch  <alriddoch@zepler.org>

	* gui/*: Updated ground work for gui widgets.

2004-05-24  James Turner  <james@worldforge.org>

	  Sprite code was lifted from Al's work in Apogee and modified to
	  work in sear.
	* Add a Compass class to the gui files, again taken from Apogee
	  and modified.
	* Change Graphics to create a compass and update it's angle.
	* Add a 'sprite' state to the state config file

2004-05-23  Al Riddoch  <alriddoch@zepler.org>

	* src/Character.h, src/Character.cpp: Add a make command that
	  allows the character to attempt to create arbitrary in game
	  objects. Also, sneak in a GNU compliant changelog entry, in
	  the hope that Simon might pick up the habbit :)

2004-05-23 James Turner <james@worldforge.org>

	* Twiddle SDL_mixer includes to work with the Mac package, and not pull in SDL/SDL.h
	  in the header file (only needed in Sound.cpp)

28th June 2002, Simon Goodall
 * Implemented basic Log object to eventually replace all cout / cerr / DEBUG msgs

18th June 2002, Simon Goodall

 * Fixed water feature
 * Fixed a bug that stopped Sear working with Stage
 * Added a change directory function to scripting engine
 * Added ability to prefix current directory to entiries on loading into config data
 * Media now moved into separate "Media Package"

16th May 2002, Simon Goodall
 * Applied patch by Alriddoch to compile under gcc 3.01. This also reduced the far clipping plane from 1000 to the more reasonable value of 100
 * Enabled two sided lighting to fix lighting problems with billboards and Impostors
 * Fog now changes colour depending upon light level
 * toggle_console now works with keys defined by braces, e.g. {F10}
 * Allows different resolutions
 * --enable-debug=no now turns off debug information from eris
 * Names now appear over currently selected object

 * console command read_config will tell system to re-read the config values in the general config loader

14th May 2002, Simon Goodall
 * Fixed bug where time cycle sped up
 * Stencil highlights now optional
 * WireFrame now uses vertex arrays

13th May 2002, Simon Goodall
 * Fixed wire frame functionality. It was potentially using uninitialised bboxes
 * Added frustum culling using sphere tests.
 * Improved lighting system. Sun now moves and has user definable dawn/dusk times
 * Added option in configure to enable debug information. Debug information is a possible cause of Sear hanging upon exit on some systems.
 * Added use of video mode querying to provide additional startup information
 * Moved lots of rendered code into vertex arrays to improve speed.
 * Removed lots of redundant rendering code from GL_Render.cpp

10th May 2002, Simon Goodall
 * Fixed bug caused by setting install directory too late

10th May 2002, Simon Goodall
 * Added version string to command line arguments. use -v or --version
 * Added help message to command line args. use -h or --help

 * Allows connection to a server on any port
 * Allow creation of characters of different type` and sex
 * Lots more messages on standard out
 * Fixed bug that used the same cally model for a given type.
 * Fixed bug where camera was not properly fixed to the vertical position of the character
 * Added wire_frame queue
 * System will downgrade none-existent model types until wire-frame is reached
 * Minimised Open GL state changes
 * Replaced OpenGL selection by a colour selection method. Improves accuracy and works with blending
 * Added halo effect to selected entities
 * Added different cursors depending upon current action
 * Changed pickup and touch to effect the next entity selected and not the current one

1st May 2002, Simon Goodall
 * Entities are now drawn according to object properties
 * New Object Properties; draw_self and draw_members; determine what gets drawn
 * Object properties file contains entries for most structures so as to hide bbox lines
 * toggle_console can now really be bound to any key instead of just back quote
 * Changed configure.in to fix INSTALLDIR being set to NONE in some cases
 * Added support for billboard / impostor styles of rendering
 * Fixed problems as seen in the sky box where seams were visible. GL_CLAMP wasn't being set properly.
 * Lots of internal changes. Hopefully much more stable now.
 * System loads a float terrain if height map not found.

27th April 2002, Simon Goodall
 * Fixed possible seg faults caused by attempting to control character before having one
 * Applied patch file by man-di fixing problems caused by previous definitions of M_PI

25th April 2002, Simon Goodall
