This major refactoring standardizes how position, size, and other arguments
are parsed across all UI components. PyArgHelpers provides consistent handling
for various argument patterns:
- Position as (x, y) tuple or separate x, y args
- Size as (w, h) tuple or separate width, height args
- Grid position and size with proper validation
- Color parsing with PyColorObject support
Changes across UI components:
- UICaption: Migrated to PyArgHelpers, improved resize() for future multiline support
- UIFrame: Uses standardized position parsing
- UISprite: Consistent position handling
- UIGrid: Grid-specific position/size helpers
- UIEntity: Unified argument parsing
Also includes:
- Improved error messages for type mismatches (int or float accepted)
- Reduced code duplication across constructors
- Better handling of keyword/positional argument conflicts
- Maintains backward compatibility with existing API
This addresses the inconsistent argument handling patterns discovered during
the inheritance hierarchy work and prepares for Phase 7 documentation.

Closes#7 - Make all UI class constructors safe:
- Added safe default constructors for UISprite, UIGrid, UIEntity, UICaption
- Initialize all members to predictable values
- Made Python init functions accept no arguments
- Added x,y properties to UIEntity
Closes#71 - Create _Drawable Python base class:
- Created PyDrawable.h/cpp with base type (not yet inherited by UI types)
- Registered in module initialization
Closes#87 - Add visible property:
- Added bool visible=true to UIDrawable base class
- All render methods check visibility before drawing
Closes#88 - Add opacity property:
- Added float opacity=1.0 to UIDrawable base class
- UICaption and UISprite apply opacity to alpha channel
Closes#89 - Add get_bounds() method:
- Virtual method returns sf::FloatRect(x,y,w,h)
- Implemented in Frame, Caption, Sprite, Grid
Closes#98 - Add move() and resize() methods:
- move(dx,dy) for relative movement
- resize(w,h) for absolute sizing
- Caption resize is no-op (size controlled by font)
