Backends: OpenGL3: Update GL3W based imgui_impl_opengl3_loader.h to load "libGL.so" and variants, fixing regression on distros missing a symlink. (#6983)

Amend 0f50b52d

Internals, Inputs: Fix for ImGuiInputFlags_RepeatUntilXXX logic when #ifdef IMGUI_DISABLE_OBSOLETE_KEYIO is not set.

Amend 8323a06e. Eager to get rid of legacy IMGUI_DISABLE_OBSOLETE_KEYIO stuff: technically it's been two years, may give it another one.

"The SDL_WindowFlags enum should be replaced with Uint32"

Shortcut: do not return true on mods changes. Internals: added ImGuiInputFlags_RepeatUntilKeyModsChange, ImGuiInputFlags_RepeatUntilKeyModsChangeFromNone, ImGuiInputFlags_RepeatUntilOtherKeyPress. (#456, #2637)

Took a while to come to this design, but it is flexible and lightweight and allow all decision to be taken a polling location. All three policies are useful.

Will make extra sense with next commit where we add ImGuiInputFlags_RepeatUntil options.

+ Misc docs/comments.

General text input is already covered by AddInputCharacter. For scancode-based key up/down info, simplest to admit that the up/down state indexes are kind of arbitrary and may not actually map perfectly to the labels on the keys.

+ removed two now unnecessary casts.

Windows: BeginChild(): Resize borders rendered even when ImGuiWindowFlags_NoBackground is specified. (#1710, #7194)

This is mostly to facilitate maintainance of #6616.

Misc: During shutdown, check that io.BackendPlatformUserData and io.BackendRendererUserData are NULL. (#7175)

Backends: Vulkan: Stop creating command pools with VK_COMMAND_POOL_CREATE_RESET_COMMAND_BUFFER_BIT as we don't reset them.

Backends: Vulkan: Added MinAllocationSize field in ImGui_ImplVulkan_InitInfo to workaround zealous validation layer. (#7189, #4238)

Backends: GLFW, Input: Use Unicode version of WndProc for get correct input for text in utf-8 code page. (#7174)

Similar to #6785, #6782, #5725, #5961 for for GLFW backend.

Drags, Sliders, Inputs: removed all attempts to filter non-numerical characters during text editing. (#6810, #7096)

Settings: Fixed an issue marking settings as dirty when merely clicking on a border or resize grip without moving it.

DragScalarN, SliderScalarN, InputScalarN, PushMultiItemsWidths: fixed multi-components width in tight space (#7120, #7121)

+ extra tweak color ColorEdit4() label. Amend 86512eac, 34646627

Backends: Vulkan: ImGui_ImplVulkan_CreateFontsTexture() calls vkQueueWaitIdle() instead of vkDeviceWaitIdle(). (#7148, #6943, #6715, #6327, #3743, #4618)
