GL_RENDERER in my application and in the egl-gears

I'm using LexSystem CI852A SBC, which has Intel 80852 integrated graphics. Default graphics driver in my system is devg-
extreme2, which is 3D accelerated.

egl-gears -info produces this information:
GL_RENDERER   = Software Rasterizer
GL_VERSION    = OpenGL ES-CM 1.0
GL_VENDOR     = QNX Software Systems
GL_EXTENSIONS = GL_OES_compressed_paletted_texture GL_OES_vertex_buffer_object GL_OES_query_matrix GL_OES_read_format

While my application tries to obtain GL_xxxx strings it get:
Vendor     : QNX Software Systems
Renderer   : Intel 82830/82845/82852/82855/82865
Version    : OpenGL ES-CM 1.0
Extensions : GL_OES_compressed_paletted_texture GL_OES_vertex_buffer_object GL_OES_query_matrix GL_OES_read_format

In both cases all OpenGL ES output is accelerated.

But on devg-svga driver GL_RENDERER string is "Unaccelerated ....", so I do not know where egl-gears got GL_RENDERER 
string.

Re: GL_RENDERER in my application and in the egl-gears

There is a problem with the information provided by egl-gears when the -info command line option is supplied. It calls 
glGetString before creating an OpenGL ES context, and before even doing eglGetDisplay. This is why it always 
inaccurately reports soft3d.
