    Add position tuple support and pos property to UI elements

    closes #83, closes #84

    - Issue #83: Add position tuple support to constructors
      - Frame and Sprite now accept both (x, y) and ((x, y)) forms
      - Also accept Vector objects as position arguments
      - Caption and Entity already supported tuple/Vector forms
      - Uses PyVector::from_arg for flexible position parsing

    - Issue #84: Add pos property to Frame and Sprite
      - Added pos getter that returns a Vector
      - Added pos setter that accepts Vector or tuple
      - Provides consistency with Caption and Entity which already had pos properties
      - All UI elements now have a uniform way to get/set positions as Vectors

    Both features improve API consistency and make it easier to work with positions.

    Standardize sprite_index property and add scale_x/scale_y to UISprite

    closes #81, closes #82

    - Issue #81: Standardized property name to sprite_index across UISprite and UIEntity
      - Added sprite_index as the primary property name
      - Kept sprite_number as a deprecated alias for backward compatibility
      - Updated repr() methods to use sprite_index
      - Updated animation system to recognize both names

    - Issue #82: Added scale_x and scale_y properties to UISprite
      - Enables non-uniform scaling of sprites
      - scale property still works for uniform scaling
      - Both properties work with the animation system

    All existing code using sprite_number continues to work due to backward compatibility.

    Fix multiple low priority issues

    closes #12, closes #80, closes #95, closes #96, closes #99

    - Issue #12: Set tp_new to NULL for GridPoint and GridPointState to prevent instantiation from Python
    - Issue #80: Renamed Caption.size to Caption.font_size for semantic clarity
    - Issue #95: Fixed UICollection repr to show actual derived types instead of generic UIDrawable
    - Issue #96: Added extend() method to UICollection for API consistency with UIEntityCollection
    - Issue #99: Exposed read-only properties for Texture (sprite_width, sprite_height, sheet_width, sheet_height, sprite_count, source) and Font (family, source)

    All issues have corresponding tests that verify the fixes work correctly.

Author: John McCardle <mccardle.john@gmail.com>

    Fix critical issues: script loading, entity types, and color properties

    - Issue #37: Fix Windows scripts subdirectory not checked
      - Updated executeScript() to use executable_path() from platform.h
      - Scripts now load correctly when working directory differs from executable

    - Issue #76: Fix UIEntityCollection returns wrong type
      - Updated UIEntityCollectionIter::next() to check for stored Python object
      - Derived Entity classes now preserve their type when retrieved from collections

    - Issue #9: Recreate RenderTexture when resized (already fixed)
      - Confirmed RenderTexture recreation already implemented in set_size() and set_float_member()
      - Uses 1.5x padding and 4096 max size limit

    - Issue #79: Fix Color r, g, b, a properties return None
      - Implemented get_member() and set_member() in PyColor.cpp
      - Color component properties now work correctly with proper validation

    - Additional fix: Grid.at() method signature
      - Changed from METH_O to METH_VARARGS to accept two arguments

    All fixes include comprehensive tests to verify functionality.

    closes #37, closes #76, closes #9, closes #79
