Graphics draw state used for blending, clipping and stencil rendering.
scissor: Option<[u32; 4]>
Scissor mask to use. If set, no pixel outside of this rectangle (in screen space) will be written to as a result of rendering.
Stencil test to use. If None, no stencil testing is done.
Blend function to use. If None, blending is disabled.
Uses alpha blending.
Draws to stencil buffer with value 255. This can be used for clipping.
For nested clipping, clear the stencil buffer and use
pub fn new_increment() -> DrawState[src]
Increases stencil buffer. This can be used for nested clipping.
pub fn new_inside() -> DrawState[src]
Tests against stencil buffer with value 255. Draws inside the shape defined by stencil buffer.
pub fn new_outside() -> DrawState[src]
Tests against stencil buffer with value 255. Draws outside the shape defined by stencil buffer.
