Reduced bunnymark limits

ADDED: GetPrevDirectoryPath()

It can break building on that platform...

Renamed internal function for consistency with similar functions.

Do not stop update/draw on window minimized

WARNING: SetConfigFlag() was reviewed to support int flags

Allow to reconfigure stdin to read input keys, this process could lead to undesired effects. Use with care.

Disabled by default.

Not sure if already corrected...

This change could break things. So, I created SUPPORT_HIGH_DPI flag to enable it (disabled by default).

Basically, it detects HighDPI display and scales all drawing (and mouse input) appropiately to match the equivalent "standardDPI" screen size on highDPI. It uses screenScaling matrix to do that.

This scaling comes with some undesired effects, like aliasing on default font text (keep in mind that font is pixel-perfect, not intended for any non-rounded scale factor).

The only solution for this aliasing would be some AA postpro filter or implementing the highDPI scaling in a different way: rendering to a texture and scaling it with FILTER_BILINEAR, check `core_window_scale_letterbox.c` example for reference.

Use at your own risk.

Basically, formating review and some variables naming to follow raylib conventions.

* Working build

* Fix build again, stop deleting files

* Hotfix crash, needs investigating

* Remove VS2015.UWP, I cannot update the project

* Lots of UWP work, added keyboard and mouse press support. Still need to finish scroll wheel, mouse position and cursor hiding, plus other stuff that I haven't seen yet.

* Implemented a ton more things, added BaseApp.h to provide common code to UWP apps.

* Remove constant window dimensions

* Enable and Disable cursor support.

* Actually use mouse delta

* Gamepad Support

* Cleaning and small tweaks

* Restore original example.

* Update comment

* Use 'Messages' to handle the cursor functions so code is more portable.

* Comment

* Comment unused message fields and use vector for mouse pos instead.

* Move messages to utils.h and use messages for everything. No more plat-specific code in raylib.h

* Tested some desktop stuff and added projection matrix updates for window resizing.

* Fixed big bad mouse bug

* Fix alt buttons and add hack to combat flickery key presses (far from perfect)

* Remove debug code

* Final commit

* Well, so I thought

* Wow, i am bad

* Remove packages folder

* Remove useless include

* Apply requested changes and fix linux build

* Try to stop packages folder

* Have we fixed the formatting properly?

* Third time's the charm?

* Where did this come from?

* Re-fix

* Autoformat is gonna kill

* Fixed XBOX ONE Support

* Fix tabs

Trying to define a global transformation matrix to scale all content for HiDPI.

Probably required for HiDPI support

Found some issues when building for web using latest emscripten 1.38.30, traced the error and found that eglGetProcAdress does not return function pointers for VAO functionality, supported by extension.

It requires more investigation but now it works (avoiding VAO usage)

Users can define their custom memory management macros.

NOTE: Most external libraries support custom macros in the same way, raylib should redefine those macros to raylib ones, to unify custom memory loading. That redefinition is only implemented as example for stb_image.h in [textures] module.

At least until a proper solution is found!

This needs to be tested on a hi-DPI monitor, probably requiring a FLAG to enable it would be a good idea...
