// Description : An offscreen buffer for rendering into. This is
|
|
// similar in function to a GraphicsWindow, except that
|
|
// the output is not visible to the user.
|
|
//
|
|
// If want_texture is passed true into the constructor,
|
|
// the GraphicsBuffer will render directly into a
|
|
// texture which can be retrieved via get_texture().
|
|
// This may then be applied to geometry for rendering in
|
|
// other windows or buffers using the same
|
|
// GraphicsStateGuardian.
