Both rounded-rectangle helpers (LabelAnnotator.draw_rounded_rectangle and the
public draw_rounded_rectangle in draw/utils) always drew two rectangles plus
four corner circles, even when border_radius is 0, which is the default for
LabelAnnotator and VertexLabelAnnotator. With a zero radius that is six cv2
calls per label per frame (the four circles are zero-radius no-ops) where one
fill rectangle does the same thing.
Add a square-corner fast path to both helpers. Output is pixel identical; only
the redundant calls go away. On a 1080p frame with 100 labels LabelAnnotator
drops from ~2.1 ms to ~1.3 ms (about 1.6x), and the rounded-rectangle call
itself is ~2.8x faster at radius 0. The radius > 0 path is unchanged.
Adds tests pinning square output to a plain rectangle for both helpers (the
public draw/utils function had no tests before).
- Rename LabelAnnotator.draw_rounded_rectangle to _draw_rounded_rectangle
(accidentally public static method — now signals internal)
- Expand draw/utils.py border_radius docstring: document <= 0 and
clamp-to-zero fast-path behaviour
- Add crash-era comment to both test files: border_radius < 0 previously
raised cv2.error; fast path silently draws square corners instead
- Add clamped-to-zero test in both test files: positive radius on a
1px-wide box clamps to 0 and triggers the fast path
- Strengthen positive-radius assertion: full center-row check + all four
corners unpainted (replaces two-pixel spot check)
- Add pytest.param(id=) slugs to all parametrize decorators per
CONTRIBUTING.md convention
- Add Google-style docstring with Args, Returns, Example to
`LabelAnnotator.draw_rounded_rectangle` (was undocumented @staticmethod)
- Rename `testdraw_*` → `test_draw_*` in `TestLabelAnnotator` to restore
consistent test naming broken by the earlier private-rename commit
- Expand `draw/utils.draw_rounded_rectangle` border_radius docstring:
note that negative values previously raised `cv2.error` and now draw
square corners silently; drop "as a fast path" implementation detail
- Add `Example:` block to `draw/utils.draw_rounded_rectangle`

This commit adds support for 4-digit and 8-digit hexadecimal color codes
with alpha channel (e.g., #FF00FF80 for 50% transparent magenta).
Changes:
- Extended Color dataclass with optional alpha field (default 255)
- Updated _validate_color_hex to accept lengths 3, 4, 6, 8
- Updated from_hex to parse 4-digit (#RGBA) and 8-digit (#RRGGBBAA) hex codes
- Modified as_hex to return #RRGGBBAA when alpha != 255
- Added as_rgba() and as_bgra() methods
- Added from_rgba_tuple() and from_bgra_tuple() class methods
- Updated __eq__ and __hash__ to include alpha channel
- Added comprehensive unit tests for all RGBA functionality
- Updated docstrings with examples of new alpha channel support
