如下代码在编译fragment shader时候会提示编译错误
vertex shader

Fragment shader

varying vec4 v_color; \n attribute vec3 v_Position; \n attribute vec4 f_Color; \n void main(void) \n { \n gl_Position = vec4(v_Position, 1.0); \n v_color = f_Color; \n }"
|
varying vec4 v_color; \n void main(void) \n { \n gl_FragColor = v_color; \n };

在fragment shader中加入精度控制，就不会出现编译错误！任何一个精度控制都可以解决编译错误（不解！）

varying (lowp/mediump/highp) vec4 v_color; \n void main(void) \n { \n gl_FragColor = v_color; \n };
