Texture2D.gl_new_from_foreign

Wraps an existing GL_TEXTURE_2D texture object as a Texture2D.

This can be used for integrating Cogl with software using OpenGL directly.

The texture is still configurable until it has been allocated so for example you can declare whether the texture is premultiplied with set_premultiplied.

<note>The results are undefined for passing an invalid gl_handle or if width or height don't have the correct texture geometry.</note>

Parameters:

ctx	A Context
gl_handle	A GL handle for a GL_TEXTURE_2D texture object
width	Width of the foreign GL texture
height	Height of the foreign GL texture
format	The format of the texture

Returns:

A newly allocated Texture2D
