Description
Hi, I'm trying to run the plugin sample under WebGL. It works fine in Editor, but the mesh is completely flat in web.
Looking at the code, it seems that modifying the mesh was intentionally disabled for WebGL.
When removing the check on SUPPORT_OPENGL_ES, I get the following error when building from Unity :
'GL_WRITE_ONLY' is undefined

Research direction
Start with PluginSource/source/RenderAPI_OpenGLCoreES.cpp lines 280-294 and reproduce the plugin sample under WebGL. Investigate the SUPPORT_OPENGL_ES check and the reported GL_WRITE_ONLY build error. Done means the sample mesh is no longer flat in WebGL and the Unity build succeeds.
