<pre>OK finally got it going. Demo may need compute and tesselation support (?) as
it queries following enums:
GL_MAX_TESS_CONTROL_TEXTURE_IMAGE_UNITS
GL_MAX_TESS_EVALUATION_UNIFORM_COMPONENTS
GL_MAX_TESS_CONTROL_UNIFORM_COMPONENTS
GL_MAX_TESS_EVALUATION_TEXTURE_IMAGE_UNITS
GL_MAX_COMPUTE_UNIFORM_COMPONENTS
GL_MAX_COMPUTE_TEXTURE_IMAGE_UNITS
After some more investigations found out that demo uses ARB_texture_multisample
(requires GL_MAX_COLOR_TEXTURE_SAMPLES > 0) and has GLSL 1.50 shaders. I get
numerous errors from failing resource file loads so I stopped there, this is
what I'm getting:
LogStreaming:Warning: Failed to read file
'../../../Engine/Content/Slate/Checkerboard.png' error.
LogStreaming:Warning: Failed to read file
'../../../Engine/Content/Slate/Icons/DefaultAppIcon.png' error.
