Sorry, I was busy for the last week.
So thanks a lot, Wade, your explanation makes totally sense.
For image_writef you write values in [0, 1] to CL_UNORM_INT8 (as internal format GL_RGBA/GL_RGBA8),
and arbitrary values to CL_FLOAT (if you defined the texture as internal format GL_RGBA32F).

Could you please post which driver for Windows, NVidia Gefore GTX 660, you use?
As I am still getting this unknown exception for "createFromGLTexture2d".
Do you use a computer with two GL chips?
