Update layer parameters
#include <gf/gf.h> int gf_layer_update( gf_layer_t layer, unsigned flags );
This function updates a layer's parameters. Changes made to a layer with the gf_layer_*() set of functions are enqueued and don't take effect until you explicitly call this function.
|Threads should not call this function between calls to gf_draw_begin() and gf_draw_end(), or a deadlock will occur.
This function will fail, if an unsupported attribute is supplied to the layer.
|To update the parameters of several layers at once, use gf_layer_update_multi().|
