Module draw_ctx 

DrawCtx — the unified drawing interface shared by the software (GfxCtx) and hardware (GlGfxCtx) rendering paths.

Every Widget::paint implementation receives a &mut dyn DrawCtx. The concrete type is either:

• GfxCtx — software AGG rasteriser (used when a widget opts into a back-buffer or when GL is unavailable).
• GlGfxCtx — hardware GL path: shapes are tessellated via tess2 and submitted as GPU draw calls.

The two implementations expose identical method signatures so that widget paint bodies are unchanged regardless of the render target.

Structs

GradientStop

One color stop in a bridge-level gradient paint.

LinearGradientPaint

Linear gradient fill paint expressed in local drawing coordinates.

PatternPaint

Repeating raster pattern paint expressed in SVG/user drawing coordinates.

RadialGradientPaint

Radial/focal gradient fill paint expressed in local drawing coordinates.

Enums

FillRule

Fill rule used when rasterizing closed paths.

GradientSpread

How a gradient behaves outside the normalized 0..=1 range.

Traits

DrawCtx

Unified 2-D drawing context.

GlPaint

Trait for widgets that want to render 3-D (or other GPU) content inline during the widget paint pass.
