Detailed Description

Flat-colored 2D geometry draw batching utility.

Internally uses GPU_SHADER_3D_FLAT_COLOR to draw single-colored rectangles, quads or lines. After adding a number of primitives with add_quad, add_wire_quad, add_line, draw them using draw. Note that draw can be called behind the scenes if number of primitives is larger than the internal batch buffer size.
