Draw a range of vertices or indexed elements.

Call this function only successful enabeling via validate_and_enable() or enable(). Capsulates glDrawArrays and glDrawElements calls. Overloaded implementations of specific renderers choose the to be used gl primitive type and whether to use an instanced draw call.

See also: render()

Parameters

count	number of to be drawn vertices/elements
start	index of first to be drawn vertex/element
use_strips	whether to generate primitives in strips (only for line or triangle primitives)
use_adjacency	whether to specify adjacency information (only for line or triangle primitives)
strip_restart_index	extraorindary index used to mark end of strips (only for strip based drawing) Strip based drawing can be combined with the use of adjacency information. Default implementation uses triangle primitives.
