Added a lot of comments, simplified call graphs.
Added full (not second-class) support for images coming from named sources (files, icon themes).
RrImage holds an RrImageSet. RrImageSet holds a bunch of RrImagePic, which are different sizes of a logical image.
RrImageSet objects can be merged if it is discovered they (will) share an RrImagePic. The RrImage objects are updated to use the new merged RrImageSet.
This changes how the imagecache works, you can load an image into it directly,
or you can load it by name (then it will load it from a file on disk).
NOTE: The name part is incomplete, as it needs to use the freedesktop.org icon
spec to search for the right file. Also to resize it should look for another
icon on disk with the same name but different size (icon themes).
Image loading is done using the Imlib2 library.
I chose Imlib2 because it's pretty fast, it's easy to use, supports many file
formats (tested xpm, gif, jpeg, png) and doesn't introduce too much bloat (it
depends :)).
I ported the patch to 3.4.7-pre3 and added some enhancements. Caching is much
better now, and icons can be disabled at compile time using --disable-imlib2
option.
What's new?
Syntax of configuration files (namely rc.xml and menu.xml) has been changed
slightly to allow users to associate icons to menu entries. This is done by
specifying path to icon file in the new "icon" attribute in "<item>" element,
e.g:
<item label="Vim" icon="/usr/share/pixmaps/vim-32.xpm">
<action name="Execute"><execute>x-terminal-emulator -T Vim -e
vim</execute></action>
</item>
If user doesn't want to display any icons in his user-defined menus, he/she can
disable icons in rc.xml, inside "<menu>" section:
<menu>
...
<showIcons>no</showIcons>
...
</menu>
Default value is "yes".
(New boolean variable "config_menu_user_show_icons" has been added to source
code.)
An icon is loaded (using menu_item_attach_icon()) when a new entry of menu is
created. Fortunately, I haven't notice any performance problems because of this
:).
Set version stuff to 3.5.0-rc1.
Copy the CHANGELOG from 3.4-working.
Rename the obt-4.0 and obrender-4.0 pkgconfig stuff to obt-3.5 and obrender-3.5
Rename the "render" directory to "obrender" so that the public headers can be
installed in <obrender/*>
