Assume the user wants to quit Dillo by default even if there are
multiple tabs.

Introduces the new option scroll_page_overlap to control the amount of
pixels of overlap when scrolling to the next or previous page.
Previously this value was taken from scroll_step, but now they are
controlled independently.

The scroll page mode changes the behavior of the mouse when clicking on
the vertical scrollbar. When enabled with scrollbar_page_mode=YES,
clicking with the left button anywhere on the vertical scrollbar will
cause the page to scroll down one page. With the right button, to scroll
up one page. Holding Shift temporarily reverts the value of the option.
|
|
Implements support for placing the vertical scrollbar on the left side
by setting scrollbar_on_left=YES on dillorc. By default, continues to be
on the right side.

Implements support for ch, rem, vw, vh, vmin and vmax units of CSS
lengths. For now the units relative to the viewport are only computed
once, and they won't change when the window is resized, but only when
the page is reloaded.

The int type doesn't have a fixed size, and is only guarantee to hold 16
bits. The current implementation assumes a size of at least 32 bits, an
uses three bits to encode the type of information stored in the rest.
To add more types of lengths we would need to take more bits from the
value itself.
A simpler approach is just to use a enumeration to take care of the type
of length and a union to encapsulate the different lengths values.

When previous TD, TH or TR tags were left open, close them when a TBODY
tag is found.

When a error causes the TLS connection to fail and stop, the conn struct
is free on Tls_close_by_key(), so writing to conn->in_connect is not
correct after that point. The solution is to only set the flag when the
it is still valid.

Instead of rejecting random characters that are not in the boundary
character set, draw a random index and select the character at that
position. The probability distribution is not perfectly uniform with
this method, but reduces the number of calls to rand() by 4 times on
average.
|
|
Makes it less likely that server implementations may break due to
unexpected boundary characters. It also allows us to avoid quotes
around the boundary.
|
|
Making the boundary string very unlikely to collide with the file to
upload allows Dillo to assume it would never be found and avoids the
expensive memmem() check.
Even if major implementations tend to add several '-' characters to
multipart/form-data boundaries, this is not enforced by RFC 2046, so it
can be increase to 70 random characters.

When a 1px value is used for the border, any zoom level that makes it
smaller makes the resulting size 0, so it disappears. Using round
instead leaves more room for zooming out before it disappears.

Long CSS stylesheets may fill the console output hiding important
messages. For now let's disable them, until we improve the mechanism to
select which messages should be enabled at runtime.

Until we have a way to enable or disable messages, we shouldn't pollute

Some website endpoints return information in JSON, which is helpful to
be read as plain text in some situations. The content can still be
downloaded to disk using the save button or the context menu.
An example is the following endpoint https://tls.browserleaks.com/tls,
which provides TLS fingerprinting information in JSON, which will change
when reloading the page (only when Dillo is linked with LibreSSL).
The original page https://tls.browserleaks.com/ uses JS and cannot be
used in Dillo.

The content="0" attribute was wrongly parsed as the URL "0". The change
makes the parser ignore a redirect with a content value that doesn't
have ";" or "url=" after the delay number.

Allows zooming in and out of pages by changing the size of all elements,
including font size, images and tables. The initial zoom is specified in
the "zoom_factor" option of dillorc.
Use the new shortcuts Ctrl+ and Ctrl- to adjust the zoom of the current
page and Ctrl 0 to reset it to 100%. When a new tab or window is opened,
the current zoom factor is inherited. Each tab retains its own zoom
factor.

The Tags array can be modified without changing the "ntags" number in

The libpng library may emit warnings when decoding a PNG image, which
are non-fatal. So far we were handling them as errors and stopping the
decoding process, which prevents Dillo from decoding some images. In

When a positive non-zero value is returned from SSL_read or SSL_write,
there is data read or written, so there is no need to check for errors.
Only in the case the return value is 0 or negative.

It may be returned when the server closes the connection, see:

It would be nice if X509_ALGOR could be made opaque at some point.
There is a somewhat clumsy accessor X509_ALGOR_get0() that allows
obtaining the ASN1_OBJECT sitting inside an X509_ALGOR. Use this
instead.

When a <meta> tag reports the "text/xhtml" content, we were correcting
it to the type guessed in TypeDet. However, the current
implementation to guess XHTML and HTML pages fails if the doctype is not
at the start of the document, falling back to text/plain.
A more robust solution is to set the TypeNorm to
"application/xhtml+xml", which can be handled by a_Mime_get_viewer() as
an HTML-like document.

The W3C validator is now protected under a CloudFlare JavaScript
challenge. However, it can be bypassed by opening directly the link
after the redirection. It doesn't work if an HTML 5 page is loaded, as
that would redirect to the Nu validator which will attempt to run the
challenge again.
So the current solution is to use the "legacy" W3C validator for HTML
4.01 or older documents and the W3C Nu validator for HTML 5 documents
only. Users would need to choose which one to use manually (at least for
now).
The WDG validator at https://www.htmlhelp.org/tools/validator/ is gone,
the server reports "Server unable to read htaccess file, denying access
to be safe", so it has been removed.
