DrawTriangles draws triangles with the given image.

The vertex floats are: 

0:  Destination X in pixels
1:  Destination Y in pixels
2:  Source X in pixels (not texels!)
3:  Source Y in pixels
4:  Bounds of the source min X in pixels
5:  Bounds of the source min Y in pixels
6:  Bounds of the source max X in pixels
7:  Bounds of the source max Y in pixels

9:  Color G
10: Color B
11: Color Y

func (*Image) Dump Uses

func (i *Image) InternalSize() (int, int)

func (*Image) IsInvalidated Uses

❖
func (i *Image) IsInvalidated() bool

func (*Image) Pixels Uses

❖
func (i *Image) Pixels() []byte

Pixels returns the image's pixels. Pixels might return nil when OpenGL error happens.
