| position | 要在其中绘制纹理的屏幕矩形。 |
| image | 要显示的 Texture。 |
| texCoords | 当图像的宽高比不适合要绘制的宽高比时，如何缩放图像。 |
| alphaBlend | 是否将图像 Alpha 混合到显示屏上（默认值）。如果为 false，则将图片绘制到显示屏上。 |
使用给定的纹理坐标在矩形内绘制纹理。
Use this function for clipping or tiling the image within the given rectangle. The second Rect texCoords describes how the texture is adjusted to fit the position Rect. The first rectangle has its size in pixels provided; the second rectangle is given in a 0.0 to 1.0 range.

using UnityEngine;
// Use DrawTextureWithTexCoords() to draw a texture. The texture is draw on the window // inside a given pixel rectangle. The size of the drawn texture is based on the value // of hor. This ranges from 0.5 to 1.25 so the bottom left half of the texture to a // greater than normal value.
