Description

This extension allows a single slice of a 3D image to be used as a 2D view in image descriptors, matching both the functionality of glBindImageTexture in OpenGL with the layer parameter set to true and 2D view binding provided by the extension EGL_KHR_gl_texture_3D_image. It is primarily intended to support GL emulation.
