|
|
// 2021-05-19: Metal: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement) |

|
// 2021-02-18: Metal: Change blending equation to preserve alpha in output buffer. |

|
|
// 2021-01-25: Metal: Fixed texture storage mode when building on Mac Catalyst. |
