- window: increase minimum size of a window with menus or fix the menu rendering so that it doesn't look odd.
- window: double-clicking on title bar to minimize isn't consistent, perhaps move to single-click on left-most collapse icon?
- window: expose contents size. (#1045)
- window: using SetWindowPos() inside Begin() and moving the window with the mouse reacts a very ugly glitch. We should just defer the SetWindowPos() call.
- window: GetWindowSize() returns (0,0) when not calculated? (#1045)
- window: freeze window flag: if not focused/hovered, return false, render with previous ImDrawList. and/or reduce refresh rate.
!- scrolling: allow immediately effective change of scroll after Begin() if we haven't appended items yet.

- drawlist: would be good to be able to deep copy of ImDrawData (we have a deep copy of ImDrawList now).
- drawlist/opt: AddRect() axis aligned pixel aligned (no-aa) could use 8 triangles instead of 16 and no normal calculation.
- drawlist: rendering: provide a way for imgui to output to a single/global vertex buffer, re-order indices only at the end of the frame (ref: https://gist.github.com/floooh/10388a0afbe08fce9e617d8aefa7d302)
- drawlist: callback: add an extra void* in ImDrawCallback to allow passing render-local data to the callback (would break API).
- main: considering adding an Init() function? some constructs are awkward in the implementation because of the lack of them.
- main: find a way to preserve relative orders of multiple reappearing windows (so an app toggling between "modes" e.g. fullscreen vs all tools) won't lose relative ordering.
// (minor and older changes stripped away, please see git history for details)
// 2018-XX-XX: Platform: Added support for multiple windows via the ImGuiPlatformIO interface.
// 2018-XX-XX: OpenGL: Offset projection matrix and clipping rectangle by draw_data->DisplayPos (which will be non-zero for multi-viewport applications).
// 2018-05-14: OpenGL: Making the call to glBindSampler() optional so 3.2 context won't fail if the function is a NULL pointer.
// 2018-03-06: OpenGL: Added const char* glsl_version parameter to ImGui_ImplOpenGL3_Init() so user can override the GLSL version e.g. "#version 150".
// 2018-02-23: OpenGL: Create the VAO in the render function so the setup can more easily be used with multiple shared GL context.
// 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplSdlGL3_RenderDrawData() in the .h file so you can call it yourself.
glBindSampler(0,0);// Rely on combined texture/sampler state.
if(glBindSampler)glBindSampler(0,0);// We use combined texture/sampler state. Applications using GL 3.3 may set that otherwise.
// Recreate the VAO every time
// (This is to easily allow multiple GL contexts. VAO are not shared among GL contexts, and we don't track creation/deletion of windows so we don't have an obvious key to use to cache them.)
// Call and read ImGui::ShowDemoWindow() in imgui_demo.cpp for demo code.
