gallium/st: add pipe_context::get_timestamp()
The VMware svga driver doesn't directly support pipe_screen::get_timestamp() but we can do a work-around. However, we need a gallium context to do so. This patch adds a new pipe_context::get_timestamp() function that will only be called if the pipe_screen::get_timestamp() function is NULL. Signed-off-by: Brian Paul <[email protected]>
