  ISSUES & TODO-LIST
  ==================
- Issue numbers (#) refer to github issues.
+ Issue numbers (#) refer to github issues listed at https://github.com/ocornut/imgui/issues
  The list below consist mostly of notes of things to do before they are requested/discussed by users (at that point it usually happens on the github)
 
+ - doc: add a proper documentation+regression testing system (#435)
  - window: maximum window size settings (per-axis). for large popups in particular user may not want the popup to fill all space.
  - window: add a way for very transient windows (non-saved, temporary overlay over hundreds of objects) to "clean" up from the global window list. perhaps a lightweight explicit cleanup pass.
  - window: calling SetNextWindowSize() every frame with <= 0 doesn't do anything, may be useful to allow (particularly when used for a single axis).

  - window/tooltip: allow to set the width of a tooltip to allow TextWrapped() etc. while keeping the height automatic.
  - draw-list: maintaining bounding box per command would allow to merge draw command when clipping isn't relied on (typical non-scrolling window or non-overflowing column would merge with previous command).
 !- scrolling: allow immediately effective change of scroll if we haven't appended items yet
- - splitter: formalize the splitter idiom into an official api (we want to handle n-way split)
+ - splitter/separator: formalize the splitter idiom into an official api (we want to handle n-way split) (#319)
  - widgets: display mode: widget-label, label-widget (aligned on column or using fixed size), label-newline-tab-widget etc.
  - widgets: clean up widgets internal toward exposing everything.

+ - columns: declare column set (each column: fixed size, %, fill, distribute default size among fills) (#513, #125)

  - textwrapped: figure out better way to use TextWrapped() in an always auto-resize context (tooltip, etc.) (git issue #249)
  - 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: add window shadows.
  - style/optimization: store rounded corners in texture to use 1 quad per corner (filled and wireframe) to lower the cost of rounding.
  - style: color-box not always square?
  - style: a concept of "compact style" that the end-user can easily rely on (e.g. PushStyleCompact()?) that maps to other settings? avoid implementing duplicate helpers such as SmallCheckbox(), etc.
  - style: try to make PushStyleVar() more robust to incorrect parameters (to be more friendly to edit & continues situation).
  - style: global scale setting.
  - text: simple markup language for color change?
+ - font: dynamic font atlas to avoid baking huge ranges into bitmap and make scaling easier.
  - font: helper to add glyph redirect/replacements (e.g. redirect alternate apostrophe unicode code points to ascii one, etc.)
  - log: LogButtons() options for specifying depth and/or hiding depth slider
