vasilito ff4ff35918 feat: track all source trees in git — full fork offline-first model 
Red Bear OS is a full fork. All sources must be available from git clone
with zero network access. Removed gitignore rules that excluded fetched
source trees under recipes/*/source/, local/recipes/kde/*/source/,
local/recipes/qt/*/source/, and vendor source trees.

Build artifacts (target/, build/, source.tar, *.o, *.so) remain excluded.

127291 files added — kernel, relibc, base, bootloader, pkgar, all KDE/Qt
frameworks, mesa, wayland, DRM drivers, and every other recipe source.

customization and application access.

>FUNCTIONAL OVERVIEW</A
></H2
><P
>Fontconfig contains two essential modules, the configuration module which
builds an internal configuration from XML files and the matching module
which accepts font patterns and returns the nearest matching font.
</P
><DIV
CLASS="SECT2"
><HR><H3
CLASS="SECT2"
><A
NAME="AEN22"
>FONT CONFIGURATION</A
></H3
><P
>The configuration module consists of the FcConfig datatype, libexpat and
FcConfigParse which walks over an XML tree and amends a configuration with
data found within. From an external perspective, configuration of the
library consists of generating a valid XML tree and feeding that to
FcConfigParse. The only other mechanism provided to applications for
changing the running configuration is to add fonts and directories to the
list of application-provided font files.
</P
><P
>The intent is to make font configurations relatively static, and shared by
as many applications as possible. It is hoped that this will lead to more
stable font selection when passing names from one application to another.
XML was chosen as a configuration file format because it provides a format
which is easy for external agents to edit while retaining the correct
structure and syntax.
</P
><P
>Font configuration is separate from font matching; applications needing to
do their own matching can access the available fonts from the library and
perform private matching. The intent is to permit applications to pick and
choose appropriate functionality from the library instead of forcing them to
choose between this library and a private configuration mechanism. The hope
is that this will ensure that configuration of fonts for all applications
can be centralized in one place. Centralizing font configuration will
simplify and regularize font installation and customization.

properties for font matching and font completion. Others are provided as a
convenience for the application's rendering mechanism.

The return value refers to newly allocated memory which should be freed by the

><P
>&#13;The format is loosely modeled after printf-style format string.
The format string is composed of zero or more directives: ordinary
characters (not "%"), which are copied unchanged to the output stream;
and tags which are interpreted to construct text from the pattern in a
variety of ways (explained below).
Special characters can be escaped
using backslash. C-string style special characters like \n and \r are
also supported (this is useful when the format string is not a C string
literal).
It is advisable to always escape curly braces that
are meant to be copied to the output as ordinary characters.&#13;</P
><P
>&#13;Each tag is introduced by the character "%",
followed by an optional minimum field width,
followed by tag contents in curly braces ({}).
If the minimum field width value is provided the tag
will be expanded and the result padded to achieve the minimum width.
If the minimum field width is positive, the padding will right-align
the text. Negative field width will left-align.
The rest of this section describes various supported tag contents
and their expansion.&#13;</P
><P
>&#13;A <I
CLASS="FIRSTTERM"
>simple</I
> tag
is one where the content is an identifier. When simple
tags are expanded, the named identifier will be looked up in
<TT
CLASS="PARAMETER"
><I
>pattern</I
></TT
> and the resulting list of values returned,
joined together using comma. For example, to print the family name and style of the
pattern, use the format "%{family} %{style}\n". To extend the family column
to forty characters use "%-40{family}%{style}\n".&#13;</P
><P
>&#13;Simple tags expand to list of all values for an element. To only choose
one of the values, one can index using the syntax "%{elt[idx]}". For example,
to get the first family name only, use "%{family[0]}".&#13;</P
><P
>&#13;If a simple tag ends with "=" and the element is found in the pattern, the
name of the element followed by "=" will be output before the list of values.
For example, "%{weight=}" may expand to the string "weight=80". Or to the empty
string if <TT
CLASS="PARAMETER"
><I
>pattern</I
></TT
> does not have weight set.&#13;</P
><P
>&#13;If a simple tag starts with ":" and the element is found in the pattern, ":"
will be printed first. For example, combining this with the =, the format
"%{:weight=}" may expand to ":weight=80" or to the empty string
if <TT
CLASS="PARAMETER"
><I
>pattern</I
></TT
> does not have weight set.&#13;</P
><P
>&#13;If a simple tag contains the string ":-", the rest of the the tag contents
will be used as a default string. The default string is output if the element
is not found in the pattern. For example, the format
"%{:weight=:-123}" may expand to ":weight=80" or to the string
":weight=123" if <TT
CLASS="PARAMETER"
><I
>pattern</I
></TT
> does not have weight set.&#13;</P
><P
>&#13;A <I
CLASS="FIRSTTERM"
>count</I
> tag
is one that starts with the character "#" followed by an element
name, and expands to the number of values for the element in the pattern.
For example, "%{#family}" expands to the number of family names
<TT
CLASS="PARAMETER"
><I
>pattern</I
></TT
> has set, which may be zero.&#13;</P
><P
>&#13;A <I
CLASS="FIRSTTERM"
>sub-expression</I
> tag
is one that expands a sub-expression. The tag contents
are the sub-expression to expand placed inside another set of curly braces.
Sub-expression tags are useful for aligning an entire sub-expression, or to
apply converters (explained later) to the entire sub-expression output.
For example, the format "%40{{%{family} %{style}}}" expands the sub-expression
to construct the family name followed by the style, then takes the entire
string and pads it on the left to be at least forty characters.&#13;</P
><P
>&#13;A <I
CLASS="FIRSTTERM"
>filter-out</I
> tag
is one starting with the character "-" followed by a
comma-separated list of element names, followed by a sub-expression enclosed
in curly braces. The sub-expression will be expanded but with a pattern that
has the listed elements removed from it.
For example, the format "%{-size,pixelsize{sub-expr}}" will expand "sub-expr"
with <TT
CLASS="PARAMETER"
><I
>pattern</I
></TT
> sans the size and pixelsize elements.&#13;</P
><P
>&#13;A <I
CLASS="FIRSTTERM"
>filter-in</I
> tag
is one starting with the character "+" followed by a
comma-separated list of element names, followed by a sub-expression enclosed
in curly braces. The sub-expression will be expanded but with a pattern that
only has the listed elements from the surrounding pattern.
For example, the format "%{+family,familylang{sub-expr}}" will expand "sub-expr"
with a sub-pattern consisting only the family and family lang elements of
<TT
CLASS="PARAMETER"
><I
>pattern</I
></TT
>.&#13;</P
><P
>&#13;A <I
CLASS="FIRSTTERM"
>conditional</I
> tag
is one starting with the character "?" followed by a
comma-separated list of element conditions, followed by two sub-expression
enclosed in curly braces. An element condition can be an element name,
in which case it tests whether the element is defined in pattern, or
the character "!" followed by an element name, in which case the test
is negated. The conditional passes if all the element conditions pass.
The tag expands the first sub-expression if the conditional passes, and
expands the second sub-expression otherwise.
For example, the format "%{?size,dpi,!pixelsize{pass}{fail}}" will expand
to "pass" if <TT
CLASS="PARAMETER"
><I
>pattern</I
></TT
> has size and dpi elements but
no pixelsize element, and to "fail" otherwise.&#13;</P
><P
>&#13;An <I
CLASS="FIRSTTERM"
>enumerate</I
> tag
is one starting with the string "[]" followed by a
comma-separated list of element names, followed by a sub-expression enclosed
in curly braces. The list of values for the named elements are walked in
parallel and the sub-expression expanded each time with a pattern just having
a single value for those elements, starting from the first value and
continuing as long as any of those elements has a value.
For example, the format "%{[]family,familylang{%{family} (%{familylang})\n}}"
will expand the pattern "%{family} (%{familylang})\n" with a pattern
having only the first value of the family and familylang elements, then expands
it with the second values, then the third, etc.&#13;</P
><P
>&#13;As a special case, if an enumerate tag has only one element, and that element
has only one value in the pattern, and that value is of type FcLangSet, the
individual languages in the language set are enumerated.&#13;</P
><P
>&#13;A <I
CLASS="FIRSTTERM"
>builtin</I
> tag
is one starting with the character "=" followed by a builtin
name. The following builtins are defined:
<P
></P
><DIV
CLASS="VARIABLELIST"
><DL
><DT
>unparse</DT
><DD
><P
>Expands to the result of calling FcNameUnparse() on the pattern.</P

associated with a font are marked constant and cannot be edited.
FcCharSets may be reference counted internally to reduce memory consumption;
this may be visible to applications as the result of FcCharSetCopy may
return it's argument, and that CharSet may remain unmodifiable.

to use with FC_WEIGHT, from an double in the 1..1000 range, resembling
the numbers from OpenType specification's OS/2 usWeight numbers, which
are also similar to CSS font-weight numbers. If input is negative,
zero, or greater than 1000, returns -1. This function linearly interpolates
between various FC_WEIGHT_* constants. As such, the returned value does not
necessarily match any of the predefined constants.

policy as well as the current configuration. Internally, fontconfig will
ignore BDF and PCF fonts which are not in Unicode (or the effectively
equivalent ISO Latin-1) encoding as those are not usable by Unicode-based
applications. The configuration can ignore fonts based on filename or
contents of the font file itself. Returns FcFalse if any of the fonts cannot be
added (due to allocation failure). Otherwise returns FcTrue.
