- text edit: field resize behavior - field could stretch when being edited? hover tooltip shows more text?
- text edit: add multi-line text edit
- tree: add treenode/treepush int variants? because (void*) cast from int warns on some platforms/settings
- tooltip: figure out a way to use TextWrapped() in a tooltip.
- settings: write more decent code to allow saving/loading new fields
- settings: api for per-tool simple persistent data (bool,int,float,columns sizes,etc.) in .ini file
! style: store rounded corners in texture to use 1 quad per corner (filled and wireframe). so rounding have minor cost.
