1. Modify DCIImage node scale parameter from INT to FLOAT type
2. Support decimal scale range from 0.1 to 10.0 with 0.1 step increment
3. Update DCIIconBuilder.add_icon_image method to handle float scale values
4. Improve DCI reader to correctly parse and display decimal scale factors
5. Update create_dci_icon function default scales to include decimal examples
6. Add comprehensive documentation for decimal scaling functionality
7. Include test cases to verify decimal scale calculation accuracy
This enhancement enables fine-grained scaling control for modern high-DPI
displays, supporting scales like 1.25x, 1.5x which are commonly used in
125% and 150% display scaling scenarios. The implementation maintains
backward compatibility with integer scales while providing smoother
scaling transitions for better visual quality.
feat: 为DCI图像添加小数缩放因子支持
1. 修改DCIImage节点的scale参数从INT类型改为FLOAT类型
2. 支持0.1到10.0范围的小数缩放，步长为0.1
3. 更新DCIIconBuilder.add_icon_image方法以处理浮点缩放值
4. 改进DCI读取器以正确解析和显示小数缩放因子
5. 更新create_dci_icon函数默认缩放值包含小数示例
6. 添加小数缩放功能的全面文档说明
7. 包含测试用例以验证小数缩放计算的准确性
此增强功能为现代高DPI显示器提供精细的缩放控制，支持1.25x、1.5x等
常用于125%和150%显示缩放场景的缩放比例。实现保持与整数缩放的向后
兼容性，同时提供更平滑的缩放过渡以获得更好的视觉质量.
