NetSurf 2.8
by Michael Drake
We're planning a NetSurf 2.8 release. Here's the current change log:
http://www.netsurf-browser.org/temp/ChangeLog
Let me know if there's anything wrong/missing.
The release is mainly a bugfix release. It addresses the following issues
with NetSurf 2.7:
- RISC OS release shipped with welcome page with broken search
- Cocoa release required Xcode to be installed for various MIME mappings
- Framebuffer release failed to load when path to cookies file was unset
- Libraries didn't build without warnings with GCC 4.6

image content handler bitmap entry refactor
by Vincent Sanders
This removes the bitmap entry from the generic content structure and
moves it into individual image handlers.
I think I found all the references but I may have missed some in a
frontend, please check
This is the last refactor step before altering the image handlers to
using a global bitmap cache.
I am unsure if adding the get_internal content method was the right
thing to do but as several places still use content_get_bitmap to
extract the underlying bitmap I thought a generic interface with
context allows for future use.
Comments or suggestions welcome.

There shouldn't be anything required of you.
Hope the move goes well. :)

Core frames progress
by Michael Drake
Iframes are now done.
Text selection in iframes is sorted. Search is not broken now, however,
it's currently not possible to search the content of frames. There is a
place to implement that now though.
Those were the last uses of the current_redraw_browser global, so I've
removed that from the source tree.
I've also fixed up iframe scrolling quite a bit.
I've started on frames. Current work in progress:
http://www.netsurf-browser.org/temp/core-frames.png
( viewing http://starfighter.acornarcade.com/ )
At the moment it just renders them. Still got to do interaction (e.g.
clicking links, scrolling), and some other things.

image handler refactor beginning
by Vincent Sanders
Add macro helper for adding image content handlers
Make all image handlers use the macro
Clean up forward references in image code
Clean up libmng handler to stop it rummaging through mime type names to change its behaviour.
Get ready for next refactor (removing bitmap pointer from content)

[PATCH] libCSS: Support for page-break-after, page-break-before, page-break-inside
by James Montgomerie
The attached patch completes support for page-break-after, page-break-before, page-break-inside in libCSS.
To do this, I've implemented a css_computed_page structure, an instantiation of which is pointed to (if used) by css_computed_style's page element (previously a NULL void *), then just filled in the property setters getters etc. Hopefully you'll find the style and intentions all in keeping with how things should be in libCSS.
Thanks,
Jamie.

Thanks for libCSS!
by James Montgomerie
Hello,
Just wanted to send an email of appreciation - I'm using libCSS (with a modified libwapcaplet and libparserutils) in my ebook rendering library "libEucalyptus". As an indie developer, it's really what's made it plausible for me to create something that can render CSS, so I'm really grateful.
It's now used in its first commercial product, K-NFB's "Blio" book reading app (http://blog.th.ingsmadeoutofotherthin.gs/introducing-blio-with-eucalyptus...). In this product, the books can be ePub XHTML, or a proprietary XML format based on XAML. libEucalyptus uses libCSS to style both (with rendering done by my own code).
I which I could contribute more back to libCSS, but it's generally done everything I've asked of it with no modifications necessary. The one area I've changed it is to add handling for the page-break properties (important for book rendering) - I'll have a patch sent to the list for that shortly.
As I said, I've also implemented a modified libwapcaplet. It's backed by iOS-native strings to allow easier interoperation with the rest of my code (by the way, it's great that libwapcaplet is factored out of libCSS like this - made this very easy to do) but I imagine that's not something that would be all that useful to others?
Thanks again!
Jamie.
