/// 技术属性允许在不同的绘图API和选项之间进行选择。在大多数平台上，唯一的选择是SC_TECHNOLOGY_DEFAULT（0）。
/// 在Windows Vista或更高版本上，可以选择SC_TECHNOLOGY_DIRECTWRITE（1）、SC_TECHNOLOGY_DIRECTWRITETAIN（2）或SC_TECHNOLOGY_DIRECTWRITEDC（3）来使用Direct2D和DIRECTWRITE API以获得更高质量的抗锯齿图形。
/// SC_TECHNOLOGY_DIRECTWRITETAIN与SC_TECHNOLOGY_DIRCTWRITE的不同之处在于，它请求在呈现帧之后保留帧，这可以防止某些卡和驱动程序出现绘图故障。SC_TECHNOLOGY_DIRECTWRITED与SC_TECHNOLOGY_DIRECTWRITEDC的不同之处在于使用DIRECTWRITE绘制到GDI DC中。
/// 在Win32上，缓冲图形被设置为该技术的合理值：GDI为开，Direct2D为关，因为Direct2D执行自己的缓冲。这可以在使用SCI_SETBUFFEREDDRAW设置技术后更改。
/// 使用DirectWrite时，可以使用SCI_SETFONTLOCALE设置适当的字体区域设置，以使用预期的语言相关字形绘制文本。
