黑洞核心 — 配置管理 + 进程控制

黑洞 Shader 所需的全部 uniform 参数 ☆ 布局必须与 HLSL cbuffer Params 精确匹配 (16字节对齐规则) ☆ HLSL 默认打包: float=4字节对齐, float4=16字节对齐, float[]=4字节对齐 因此 float4 前需要确保在 16 字节边界

A single draw command list (generally one per window, conceptually you may see this as a dynamic "mesh" builder)

Data shared among multiple draw lists (typically owned by parent ImGui context, but you may create one yourself)

Helper to split a draw list into different layers which can be drawn into out of order, then flattened back.

A single vertex (pos + uv + col = 20 bytes by default. Override layout with IMGUI_OVERRIDE_DRAWVERT_STRUCT_LAYOUT)

This structure is likely to evolve as we add support for incremental atlas updates. Conceptually this could be in ImGuiPlatformIO, but we are far from

Configuration data when adding a font or merging fonts

A single font glyph (code point + coordinates within in ImFontAtlas + offset)

X/Y enums are fixed to 0/1 so they may be used to index ImVec2
