- Style: Made window close button cross slightly smaller.

- ImDrawList: Added ImDrawCmd::VtxOffset value to support large meshes (64k+ vertices) using 16-bits indices.
|
||||
To enable the feature, the renderer back-end needs to set 'io.BackendFlags |= ImGuiBackendFlags_HasVtxOffset'
|
||||
and honor the ImDrawCmd::VtxOffset field. Otherwise the value will always be zero.

The renderer back-end needs to set 'io.BackendFlags |= ImGuiBackendFlags_RendererHasVtxOffset' to enable

this, and honor the ImDrawCmd::VtxOffset field. Otherwise the value will always be zero.
|
||||
This has the advantage of preserving smaller index buffers and allowing to execute on hardware that do not
|
||||
support 32-bits indices. Most examples back-ends have been modified to support the VtxOffset field.
|
||||
- ImDrawList: Added ImDrawCmd::IdxOffset value, equivalent to summing element count for each draw command.
