- drawlist: end-user probably can't call Clear() directly because we expect a texture to be pushed in the stack.
|

- drawlist: 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).

- drawlist: make it easier to toggle AA per primitive, so we can use e.g. non-AA fill + AA borders more naturally
|
||||
- drawlist: non-AA strokes have gaps between points (#593, #288), especially RenderCheckmark().
|
||||
- drawlist: would be good to be able to deep copy of ImDrawData (we have a deep copy of ImDrawList now).

- input text multi-line: don't directly call AddText() which does an unnecessary vertex reserve for character count prior to clipping. and/or more line-based clipping to AddText(). and/or reorganize TextUnformatted/RenderText for more efficiency for large text (e.g TextUnformatted could clip and log separately, etc).

- input text multi-line: behave better when user changes input buffer while editing is active (even though it is illegal behavior). namely, the change of buffer can create a scrollbar glitch (#725)
