Detailed Description

Specifies the size of rasterized points. May either be set statically or by shader programs.

When the sizeMode property is set to SizeMode::Fixed, the value is set using glPointSize(), if available. When using SizeMode::Programmable, gl_PointSize must be set within shader programs, the value provided to this RenderState is ignored in that case.
