The code to print blocks in now in theme layout.php files. (Or in
moodle_core_renderer::handle_legacy_theme)
Code for printing blocks everywhere else has been stripped out.

The way the HTML for a block instance is generated has been cleaned
up a lot. Now, the block_instance generates a block_contents
object which gives a structured representation of the block,
and then $OUTPUT->block builds all the HTML from that.
How theme config.php files specify the layout template and block
regions by page general type has been changed to be even more flexible.
Further refinement for how the theme and block code gets initialised.
Ability for scrits to add 'pretend blocks' to the page. That is,
things that look like blocks, but are not normal block_instances.
(Like the add a new block UI.)
Things that are still broken:
* some pages in lesson, quiz and resource. I'm working on it.
* lots of developer debug notices pointing out things that
need to be updated.
moodle_url::get_query_string() and moodle_url::out() now accept new
optional parameter. Backwards compatible. This is needed so we can use returned URL
during redirect() which expects unescaped ampersands.
This is part of http://docs.moodle.org/en/Development:Theme_engines_for_Moodle%3F
$THEME is now initialised at the same time as $OUTPUT. Old functions like
theme_setup are deprecated in favour of methods on $PAGE. There is a new
theme_config class in outputlib.php that deals with loading the theme config.php file.
CSS used to be served by themes styles.php files calling a function in weblib.php.
Now it works by each theme's styles.php file doing
$themename = basename(dirname(__FILE__));
require_once(dirname(__FILE__) . '/../../theme/styles.php');
which is less code to be copied into each theme. (Old-style styles.php files still
work thanks to some code in deprecatedlib.php.)
Admin UI for choosing a theme cleaned up.
A couple of theme-specific hard-coded hacks like $THEME->cssconstants and
$THEME->CSSEdit have been replaced by a more generic $THEME->customcssoutputfunction
hook. See examples at the end of outputlib.php
Also:
* Fix setting the theme in the URL, which seems to have been broken since 1.9.
* Fix up errors on a few pages caused by the new initialisation order.
* MDL-19097 moodle_page::set_course should not set $COURSE unless it is $PAGE.
* httpsrequired() from moodlelib.php moved to $PAGE->https_required().
* Move has_started() method to the renderer base class.
* Further fixes to display of early errors.
* Remove print_header/footer_old from weblib. I did not mean to commit them before.
The custom-corners-specific code now in theme/customcornser/renderers.php
and lib/deprecatedlib.php.
Also, $CFG->pixpath is now causing more problems than ever. If it is
giving your problems, please call $OUTPUT->initialise_deprecated_cfg_pixpath()
as a temporary fix. As you can imagine, we are thinking about a better
long-term fix, which is why that method as a silly, and easy to grep name.
Also, part of the change from weblib.php functions to $OUTPUT-> methods.
This is part of http://docs.moodle.org/en/Development:Theme_engines_for_Moodle%3F
This is a big change, and the result is not perfect yet. Expect some debugging output
on some pages.
The main part of these changes are that $OUTPUT->header now looks for a file
in the theme called layout.php, rather than header.html and footer.html. Also
you can have special templates for certain pages like layout-home.php. There is
fallback code for Moodle 1.9 themes, so they still work.
A few of the old arguments to print_header are no longer supported. (You get an
exception if you try to use them.) Sam H will be cleaning those up.
All the weblib functions that have been replaced with $OUTPUT-> have version in
deprecatedlib, so existing code will go on working for the foreseeable future.
There is a new implementation of require_js in lib/deprecatedlib.php,
based on $PAGE->requires.
There were a few other recently introduced functions in lib/weblib.php,
namely print_js_call, print_delayed_js_call, print_js_config and
standard_js_config. These have been removed, since they were never in
a stable branch, and all the places that used them have been changed
to use the newer $PAGE->requires->... methods.
get_require_js_code is also gone, and the evil places that were calling
it, even though it is an internal function, have been fixed.
Also, I made some minor improvements to the code I committed yesterday
for MDL-16695.
All that remains is to update all the places in core code that are
still using require_js.
(This commit also fixes the problem where the admin tree would not
start with the right categories expanded.)
