// CHANGELOG

// (minor and older changes stripped away, please see git history for details)
|

// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
|
||||
// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
|
||||
// 2021-05-19: DirectX11: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
|
||||
// 2021-02-18: DirectX11: Change blending equation to preserve alpha in output buffer.
