//---- Define constructor to convert your string type to ImStrv (which is a non-owning begin/end pair)
// This will be inlined as part of ImStrv class declaration.
// This has two benefits: you won't need to use .c_str(), if length is already computed it is faster.

//---- Use 32-bit vertex indices (default is 16-bit) is one way to allow large meshes with more than 64K vertices.
// Your renderer backend will need to support it (most example renderer backends support both 16/32-bit indices).
// Another way to allow large meshes while keeping 16-bit indices is to handle ImDrawCmd::VtxOffset in your renderer.
