void gst_gl_filter_draw_texture (GstGLFilter *filter,GLuint texture,guint width,guint height);
Draws texture
 into the OpenGL scene at the specified width
 and height
.
void gst_gl_filter_render_to_target (GstGLFilter *filter,gboolean resize,GLuint input,GLuint target,GLCB func,gpointer data);
Transforms input
 into output
 using func
 on through FBO.  resize
 should
only ever be TRUE whenever input
 is the input texture of filter
.
void gst_gl_filter_render_to_target_with_shader (GstGLFilter *filter,gboolean resize,GLuint input,GLuint target,GstGLShader *shader);
Transforms input
 into output
 using shader
 on FBO.  resize
 should
only ever be TRUE whenever input
 is the input texture of filter
.

Perform automatic upload if needed, call filter_texture vfunc and then an automatic download if needed.
typedef struct _GstGLFilter GstGLFilter;
GstGLFilter is a base class that provides the logic of getting the GL context from downstream and automatic upload/download for non-GstGLMemory GstBuffers.
