## Description

Cogl allows creating and operating on offscreen framebuffers.

## Details

### cogl_offscreen_new_to_texture ()

    CoglHandle          cogl_offscreen_new_to_texture       (CoglHandle handle);

This creates an offscreen buffer object using the given texture as the primary color buffer. It doesn't just initialize the contents of the offscreen buffer with the texture; they are tightly bound so that drawing to the offscreen buffer effectivly updates the contents of the given texture. You don't need to destroy the offscreen buffer before you can use the texture again.

Note: This does not work with sliced Cogl textures.

`handle` : | A CoglHandle for a Cogl texture
Returns : | a CoglHandle for the new offscreen buffer or `COGL_INVALID_HANDLE` if it wasn't possible to create the buffer. [transfer full]

### cogl_is_offscreen ()

    gboolean            cogl_is_offscreen                   (CoglHandle handle);

Determines whether the given CoglHandle references an offscreen buffer object.

`handle` : | A CoglHandle for an offscreen buffer
Returns : | `TRUE` if the handle references an offscreen buffer, `FALSE` otherwise
