// 2021-XX-XX: Platform: Added support for multiple windows via the ImGuiPlatformIO interface.
|
||||
// 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).
|
||||
// 2020-01-17: Inputs: Disable error callback while assigning mouse cursors because some X11 setup don't have them and it generates errors.
|
||||
// 2019-12-05: Inputs: Added support for new mouse cursors added in GLFW 3.4+ (resizing cursors, not allowed cursor).
|
||||
// 2019-10-18: Misc: Previously installed user callbacks are now restored on shutdown.
