Summary description: Modern spot color support for the xcolor package

Announcement text: ----------------------------------------------------------------------

The spotxcolor package has been updated to version 1.0.
This release brings major enhancements for complex graphics,
ensuring that your spot colors remain print-safe across all
major TeX engines.

## Major Changes in v1.0 (since v0.14):

* Advanced TikZ/PGF Support: Integrated comprehensive patches to
resolve ColorSpace dictionary collisions with PGF. Spot colors
now work seamlessly with complex TikZ graphics, basic shapes,
and function graphs without destroying PDF resources.

* CMYK Pattern Fills: Injected a core patch into PGF to force
uncolored patterns (both legacy patterns and modern patterns.meta)
to use CMYK instead of hardcoded RGB. This guarantees that spot
colors used in TikZ patterns safely fall back to CMYK, preventing
print separation issues.

* Explicit Driver Support: Improved compatibility and explicit
fallback mechanisms for dvipdfmx, pdftex, and luatex.

* License: Updated the package license to LPPL v1.3c or later.

Version: 1.4 2026-03-17
License: lppl1.3c

Summary description: Modern spot color support for the xcolor package

Announcement text: ----------------------------------------------------------------------

Changes since v1.0:

- Fixed spot color output for \color, \textcolor, and \pagecolor.
In v1.0, these commands fell back to CMYK values instead of
producing true PDF Separation color space operators.
As of v1.4, all standard xcolor commands rCo including tinted
expressions like DIC161s!50 rCo correctly generate spot color
output on all engines (pdfTeX, LuaTeX, XeTeX, and dvipdfmx).

- Fixed spot color output for PGF/TikZ drawing commands.
TikZ \fill, \draw, and low-level PGF color commands now produce
spot color operators for both fill and stroke independently.

- Fixed spot color output for PGF uncolored pattern fills.
Hatching and dot patterns (both legacy `patterns` and modern
`patterns.meta` libraries) now use a [/Pattern [/Separation ...]]
color space, producing true spot color output in pattern fills.

- Added user manual (spotxcolor.tex) with a feature/limitation
summary table.
