Log/Capture: Fixed LogXXX functions 'auto_open_depth' parameter being treated as an absolute tree depth instead of a relative one. Fixed CollapsingHeader trailing ascii representation being "#" instead of "##". Minor tidying up the of code.

 - TabBar: Fixed a crash when using BeginTabBar() recursively (didn't affect docking). (#2371)
 - TabBar: Added extra mis-usage error recovery. Past the assert, common mis-usage don't lead to
  hard crashes any more, facilitating integration with scripting languages. (#1651)
+- Log/Capture: Fixed LogXXX functions 'auto_open_depth' parameter being treated as an absolute
+  tree depth instead of a relative one.
+- Log/Capture: Fixed CollapsingHeader trailing ascii representation being "#" instead of "##".
 - Examples: OpenGL: Fix for OSX not supporting OpenGL 4.5, we don't try to read GL_CLIP_ORIGIN
  even if the OpenGL headers/loader happens to define the value. (#2366, #2186)

 - style: gradients fill (#1223) ~ 2 bg colors for each fill? tricky with rounded shapes and using textures for corners.
 - style editor: color child window height expressed in multiple of line height.

- - log: LogButtons() options for specifying depth and/or hiding depth slider
 - log: have more control over the log scope (e.g. stop logging when leaving current tree node scope)
 - log: be able to log anything (e.g. right-click on a window/tree-node, shows context menu? log into tty/file/clipboard)
 - log: let user copy any window content to clipboard easily (CTRL+C on windows? while moving it? context menu?). code is commented because it fails with multiple Begin/End pairs.

 - filters: set a current filter that tree node can automatically query to hide themselves
 - filters: handle wild-cards (with implicit leading/trailing *), reg-exprs
 - filters: fuzzy matches (may use code at blog.forrestthewoods.com/4cffeed33fdb)
