std::transform does not correctly handle code points outside of the ASCII range.
Poco::cat is faster than using std::string + operator.
Less code, easier maintenance.
Use the C++ std::string preferred method.
Update signal handling

- Pass signal number as exit code w/ std::exit()
- Change global signal handler name to ofSignalHandler().
Tabs to match local code style.

Feature utf8 string
Fix for #3088.
Merge pull request #3163 from bakercp/bugfix-ofAppGLFWWindow_drop_cb

Fix for #3088.
fix pragma to allow tabs for whitespace

+ Uses the more permissive regexp symbol \s to denote whitespace instead of literal whitespace, this way, tabs in the #pragma directive won't trip up the shader includes preprocessor.
remove unnecessary glGet

+ glGet() directives stall the GL pipeline by implicitly flushing the command buffer and should not be used in the draw loop.

+ I've tested performance on this with Nsight and it seems that the earlier claim for better perf is outdated, especially when GPU-CPU asynchronicity and best possible GPU load balancing is desired.
Added iOS version-specific handling for updating the GLView bounds and center after orientation changes as described in issue #3158
