irrlicht ogles2 win32 work good~~~

Win32 libGLESv2.dll use AngleProject instruction set with SSE(not SSE2)

you might want to consider code tags.

Code tags might help, but more important would be a description of why this code is posted. What is this about? Is it about a bug in Irrlicht? Something we should change?

When you post code without explaining why you post it - I just have no idea what it is about. We need at least some context.

surface.cpp's bug from git clone https://chromium.googlesource.com/angle/angle

its a ogles2 GLSL to HLSL tool~~~

So you just post more code but still don't write *why* you post that code? I remember we had that exact same discussion in the past...

Really - as long as you don't explain what this is about I have no clue what this is about.

AngleProject provide GLSL to win32 HLSL

i modify AngleProject for irrlicht on win32 using

after building AngleProject will generate libGLESv2.dll and libGLESv2.lib we can link this lib~~~

libGLESv2.dll and libGLESv2.lib are OGLES2 simulator on win32

it's easier debug GLSL shading language on win32
