Previously content handler debugging features were accessed by global
variables. This allows the setting of debugging parameters via a
content API giving per content control over debugging features.
Currently only used by the html content handler to toggle global
redraw debugging.
This script can be used to generate gource visualisation mpeg
files. The visualisation looks pretty and goes down well at trade
shows as a background on the video projector.
The frontends previously had to use an html renderer API to get the
encoding of a content. This also required the explicit checking of the
contents type rather than using the existing content API to abstract
this knowledge.
This cleans up this header and moves the functionality into more
useful places while reducing the include complexity but only pulling
in whats required.
Update the API which allows frontends to acquire the page features
(images, link urls or form elements) present at the given coordinates
within a browser window.
By making this an explicit browser_window API and using the browser.h
header for the associated data structure with a more appropriate API
naming the usage is much more obvious and contained.
Additionally the link url is now passed around as a nsurl stopping it
being converted from nsurl to text and back again several times.
When updating the RISC OS frontend to using nsurl for its menu
operations (as part of getting rid of url_nice) the check for
null (empty) url strings in the url under the mouse was omitted
leading to a crash.
Additionaly a use of url where current_menu_url was intended was
missed leading to crashes when "open in new window" was used.
The local history interface now reports errors to its callers isntead
of inconsistantly waning the user occasionally on error.
The documentation comemhts were also updated to match reality
It has come to my attention that some websites (eg amigakit.com) are using marginally more than the 96K stack space set previously. This should give plenty of breathing space.
The browser window common initialisation code returns error codes which
were being ignored. The errors were additionally being reported via
warn_user in inappropriate places within browser history construction.
