这个是顶点绘制法
我稍微扯下吧
VertexMode 顶点类型 比如他是三角形（连续3个顶点）或者 四边形 （连续4个顶点）等等
vertexCount 顶点数 总共有多少个顶点绘制。
verts[] 顶点数组 [0,0,0,1,1,0,...] 前面有xy 3组 如果是类型是三角形 他就构成一个三角形的绘制基元，往后类推。
vertOffset 顶点数据 起始位置 可能全部绘制，也可能只绘制部分顶点。与 vertexCount 配置使用 一般为0
texs[] 纹理数组 就是对图片等进行采样，然后去渲染顶点。（这个比较复杂，需要了解下 比如opengl渲染原理。）
texOffset 同上offset 就是偏移量
colors[] 颜色数组 直接用颜色渲染顶点
colorOffset 同上offset 就是偏移量
indices[] 顶点索引 可能只绘制部分顶点 这个就是存放那些顶点的index ， 即verts[index]
indexOffset 同上offset 就是偏移量
indexCount 绘制多少个索引点。
paint 这个只有 texs[] 不空 必须提供， 提供图片之类东西 采样。更多的知识 你可以搜索下 图像渲染基础。
