The blend equation is used to determine how a new pixel is combined with a pixel already in the framebuffer.

Constant	Value	Description
`Qt3DRender::QBlendEquation::Add`	`0x8006`	GL_FUNC_ADD
`Qt3DRender::QBlendEquation::Subtract`	`0x800A`	GL_FUNC_SUBTRACT
`Qt3DRender::QBlendEquation::ReverseSubtract`	`0x800B`	GL_FUNC_REVERSE_SUBTRACT
`Qt3DRender::QBlendEquation::Min`	`0x8007`	GL_MIN
`Qt3DRender::QBlendEquation::Max`	`0x8008`	GL_MAX

Holds the blend function, which determines how source and destination colors are combined.

Access functions:

Qt3DRender::QBlendEquation::BlendFunction	blendFunction() const
void	setBlendFunction(Qt3DRender::QBlendEquation::BlendFunction blendFunction)

Notifier signal:

void	blendFunctionChanged(Qt3DRender::QBlendEquation::BlendFunction blendFunction)

The constructor creates a new blend state object with the specified parent.
