    • Techniques for hardware accelerated caret rendering are described in which a system based caret is emulated using hardware acceleration technology. The hardware accelerated caret can be rendered using dedicated graphics processing hardware to look and feel like a system caret. This can involve using pixel shaders to produce the hardware accelerated caret and a employing a back-up texture to remove the caret after it is drawn and cause the caret to blink. In addition, rendering of the caret can be coordinated with other animations and/or other presentations of a frame buffer to piggy back drawing of the caret onto other drawing operations. This can reduce the number of times the frame buffer is presented and therefore improve performance.
    • 描述了用于硬件加速插入符号渲染的技术,其中使用硬件加速技术来模拟基于系统的插入符号。 硬件加速插入符号可以使用专用的图形处理硬件来渲染,看起来像一个系统插入符号。 这可能涉及使用像素着色器产生硬件加速插入符号,并采用后备纹理在绘制后删除插入符号,并导致插入符号闪烁。 此外,插入符号的呈现可以与框架缓冲器的其他动画和/或其他呈现进行协调,以将插入符号的图形背面绘制到其它绘图操作上。 这可以减少帧缓冲区呈现的次数,从而提高性能。
