drawClippedTriangles

Render a triangle list using the idx indexes into the vtx vertexes clipped to to clipr (if given). Vertex positions and clipr are in physical pixels. If texture is given, the vertexes uv coords are normalized (0-1). clipr (if given) has whole pixel values.

Parameters

self:Backend: Backend
texture:?dvui.Texture: ?dvui.Texture
vtx:[]const dvui.Vertex: []const dvui.Vertex
idx:[]const dvui.Vertex.Index: []const dvui.Vertex.Index
clipr:?dvui.Rect.Physical: ?dvui.Rect.Physical
