---------------
- Added retain/release mechanism to RImage by adding RRetainImage() and
RReleaseImage(). RDestroyImage() is an alias to RReleaseImage() now, but
will be removed in a future release because it no longer fits with the
semantics. Will be kept for a while to allow a smoother transition.
More about in wrlib/NEWS
For WINGs:
----------
- Small API change:
1. Renamed WMSetApplicationIconImage(), WMGetApplicationIconImage() and
WMSetWindowMiniwindowImage() to respectively WMSetApplicationIconPixmap(),
WMGetApplicationIconPixmap() and WMSetWindowMiniwindowPixmap()
They operate on a WMPixmap which is practically an X Pixmap with no alpha
channel information and the new name is more suggestive and also leaves
room for the new functions added for operating on images with alpha info.
2. Added WMSetApplicationIconImage() and WMGetApplicationIconImage() which
operate on an RImage and store alpha information too.
3. Added WMGetApplicationIconBlendedPixmap() which will take the image with
alpha set by WMSetApplicationIconImage() and will blend it with a color.
If color is NULL it will blend using the default panel color (#aeaaae)
All these changes will allow WINGs to handle images with alpha blending
correctly in panels and wherever else needed. More about in WINGs/NEWS.
- updated panels to use the newly available RImages if present and fallback
to old WMPixmaps if not, to properly show alpha blended images.
- replaced some still left malloc's with wmalloc's.
For Window Maker:
-----------------
- Fixed wrong mapping position of the "Docked Applications Panel" for some
icons.
- Smoother animation for the smiley =)
- Made images with alpha blending be shown correctly in the panels and the
icon chooser.
- The icon image set to be shown in panels ("Logo.WMPanel") will be
automatically updated if its entry in WMWindowAttributes changes (without
a need to restart as until now).
*** Note!!! ***
If you are developing applications with one of libwraster or libWINGs
then you should look to wrlib/NEWS and WINGs/NEWS to see what changed
and how should you update your code.
code like
*ptr++ = *ptr++ = *ptr++ = color;
is wrong, because there is no guarantee that ptr will be incremented
_between_ the assignment operations. it can be incremented after all
assignment operations as well. Because of this both of these are valid
implementations for a compiler:
a. assign, increment, assign, increment, assign, increment
b. assign, assign, assign, increment by 3
In case b. only the first memory location of the 3 will be modified, being
assigned 3 times the same value, while the other 2 remain unchanged.
For example egcs-2.91.66 (and possibly gcc-2.95.x too) implement this in
the second way (like in case b.)
Also the order in which the assignement is made is undefined (left to right
or right to left).
this fixed the problem we had with greyscale jpegs showing up in red,
and possibly other problems related to pseudocolor and greyscale displays.
