- drawlist: end-user probably can't call Clear() directly because we expect a texture to be pushed in the stack.
- examples: directx9: save/restore device state more thoroughly.
- examples: window minimize, maximize (#583)
- optimization: add clipping for multi-component widgets (SliderFloatX, ColorEditX, etc.). one problem is that nav branch can't easily clip parent group when there is a move request.
- optimization: add a flag to disable most of rendering, for the case where the user expect to skip it (#335)
- optimization: use another hash function than crc32, e.g. FNV1a
- optimization/render: merge command-lists with same clip-rect into one even if they aren't sequential? (as long as in-between clip rectangle don't overlap)?
- optimization: turn some the various stack vectors into statically-sized arrays
- optimization: better clipping for multi-component widgets
