  Here is a change-log of API breaking changes, if you are using one of the functions listed, expect to have to fix some code.
  
  - 2015/07/05 (1.42) - switched rendering data to use indexed rendering. this is saving a fair amount of CPU/GPU and enables us to get anti-aliasing for a marginal cost.
-                       this necessary change will break your rendering function! the fix should be very easy.
+                       this necessary change will break your rendering function! the fix should be very easy. sorry for that :(
                      - if you are using a vanilla copy of one of the imgui_impl_XXXX.cpp provided in the example, you just need to update your copy and you can ignore the rest.
                      - the signature of io.RenderDrawListsFn has changed! 
                             ImGui_XXXX_RenderDrawLists(ImDrawList** const cmd_lists, int cmd_lists_count)
                        became:
                             ImGui_XXXX_RenderDrawLists(ImDrawData* draw_data). 
-                     - the ImDrawData structure contains 'cmd_lists', 'cmd_lists_count' and more (that were previously passed as parameters).
+                            argument   'cmd_lists'        -> 'draw_data->cmd_lists'
+                            argument   'cmd_lists_count'  -> 'draw_data->cmd_lists_count'
+                            ImDrawList 'commands'         -> 'cmd_buffer'
+                            ImDrawCmd  'vtx_count'        -> 'elem_count' (same value, multiple of 3)
                      - the ImDrawList and ImDrawCmd structures also have changed to allow for indexed rendering.
-                       each ImDrawList now contains both a vertex buffer (vtx_buffer) and an index buffer (idx_buffer).
-                       renamed the 'vtx_count' field of ImDrawCmd to 'elem_count' to reflect this. Render 'elem_count' (multiple of 3) using indices from the index buffer.
+                       each ImDrawList now contains both a vertex buffer (vtx_buffer) and an index buffer (idx_buffer). For each command, render elem_count/3 triangles using indices from the index buffer.
                      - if you REALLY cannot render indexed primitives, you can call the draw_data->DeIndexAllBuffers() method to de-index your buffer. This is slow and a waste of CPU/GPU. Prefer using indexed rendering!
                      - refer to code in the examples/ folder or ask on the github if you are unsure of how to upgrade.
  - 2015/07/02 (1.42) - renamed SetScrollPosHere() to SetScrollFromCursorPos(). Kept inline redirection function (will obsolete).
