easy_profiler/profiler_gui/arbitrary_value_inspector.h
Victor Zarubkin 272c0ceab1 [ui] fixed slider freeze after load new file in "Zoom" mode; 
[core] #157 added new build flag EASY_OPTION_TRUNCATE_RUNTIME_NAMES which will prevent from crash for very big block names, but will reduce performance. Disabled by default because of very rare use case;
[core] #157 added new build flag EASY_OPTION_CHECK_MAX_VALUE_SIZE for EASY_VALUE arrays and strings - same as the flag above for block names. Also disabled by default;
