 Breaking Changes:
 
- - Changed default ImTextureID_Invalid value to -1 instead of 0 if not #define-d.
-    (#9293, #8745, #8465, #7090)
-   - It seems like a better default since it will work with backends storing
-     indices or memory offsets inside ImTextureID, where 0 might be a valid value.
-   - If this is causing problem with e.g your custom ImTextureID definition, you can
-     add '#define ImTextureID_Invalid 0' to your imconfig.h + PLEASE report this to GitHub.
-   - If you have hardcoded e.g. 'if (tex_id == 0)' checks they should be updated.
-     e.g. OpenGL2, OpenGL3 and SDLRenderer3 backends incorrectly had 'IM_ASSERT(tex->TexID == 0)'
-     lines which were replaced with 'IM_ASSERT(tex->TexID == ImTextureID_Invalid)'.
-     If you have copied or forked backends consider fixing locally. (#9295)
  - Separator(): fixed a legacy quirk where Separator() was submitting a zero-height
    item for layout purpose, even though it draws a 1-pixel separator.
