linux系统swiftshader开关编译Hello2D生成图片不一致的问题

[1ceOcean]

在linux/CMakeLists.txt内将

set(TGFX_USE_SWIFTSHADER ON)

改为

set(TGFX_USE_SWIFTSHADER OFF)

后编译运行两次生成的图片ConicGradient，SimpleLayerTree不一致是正常情况么（第二排的是关闭Swiftshader生成的）？

感谢反馈，这里是跑的测试用例吗，有没有具体代码呢

让AI帮忙调试了一下，应该是真实硬件环境下 OpenGL ES shader 的精度问题。

直接使用hparty_conic_repro分支构建运行测试结果：
[ConicHollowRepro] centerAlpha=0 q1=0 q2=0

把GLSLFragmentShaderBuilder::GLSLFragmentShaderBuilder里precision mediump float;改为precision highp float;

--- a/src/gpu/glsl/GLSLFragmentShaderBuilder.cpp
+++ b/src/gpu/glsl/GLSLFragmentShaderBuilder.cpp
@@ -28,7 +28,7 @@ GLSLFragmentShaderBuilder::GLSLFragmentShaderBuilder(ProgramBuilder* program)
   auto glProgram = static_cast<GLSLProgramBuilder*>(program);
   auto shaderCaps = glProgram->getContext()->shaderCaps();
   if (shaderCaps->usesPrecisionModifiers) {
-    setPrecisionQualifier("precision mediump float;");
+    setPrecisionQualifier("precision highp float;");
   }
 }

之后跑出来的结果是：
[ConicHollowRepro] centerAlpha=255 q1=255 q2=255

重新编译运行Hello2D之后图片结果和SwiftShder一致.

找到问题就好解决，我这边更新了下分支，把和坐标计算相关的都设置成highp了，你可以试试看还有没有问题

[1ceOcean]

bugfix/hparty_shader_precision分支下的CanvasTest.ConicGradientFillHollow已经成功通过，linux/下的几个Layer也和SwiftShader输出一致了
