Added ColorPicker3/ColorPicker4, refactoring ColorEdit3/ColorEdit4 adding a bunch of flags and access to picker (wip #346)
Still pretty much experimenting so may break API

Here is a change-log of API breaking changes, if you are using one of the functions listed, expect to have to fix some code.
|
||||
Also read releases logs https://github.com/ocornut/imgui/releases for more details.
|
||||
|
||||
- 2016/02/21 (1.48) - removed ColorEditMode() and ImGuiColorEditMode in favor of ImGuiColorEditFlags and parameters to ColorEdit*() functions
|
||||
- replaced ColorEdit4() third parameter 'bool show_alpha=true' to 'ImGuiColorEditFlags flags=0x01' where ImGuiColorEditFlags_Alpha=0x01 for dodgy compatibility
|
||||
- 2016/01/23 (1.48) - fixed not honoring exact width passed to PushItemWidth(), previously it would add extra FramePadding.x*2 over that width. if you had manual pixel-perfect alignment in place it might affect you.
|
||||
- 2015/12/27 (1.48) - fixed ImDrawList::AddRect() which used to render a rectangle 1 px too large on each axis.
|
||||
- 2015/12/04 (1.47) - renamed Color() helpers to ValueColor() - dangerously named, rarely used and probably to be made obsolete.
