// CHANGELOG
// (minor and older changes stripped away, please see git history for details)
// 2021-05-19: OpenGL: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
// 2021-04-06: OpenGL: Don't try to read GL_CLIP_ORIGIN unless we're OpenGL 4.5 or greater.
// 2021-02-18: OpenGL: Change blending equation to preserve alpha in output buffer.
// 2021-01-03: OpenGL: Backup, setup and restore GL_STENCIL_TEST state.
// 2020-10-23: OpenGL: Backup, setup and restore GL_PRIMITIVE_RESTART state.
// 2020-10-15: OpenGL: Use glGetString(GL_VERSION) instead of glGetIntegerv(GL_MAJOR_VERSION, ...) when the later returns zero (e.g. Desktop GL 2.x)
