Supported UTF8 range equivalent to [128..255] (80h..FFh)
Exposed and renamed text function GetGlyphIndex()
Renamed spriteFont parameter name to simply font
Small security check on transmission mission ending screen

Rename: GetHexValue() renamed to ColorToInt()
Added: ColorToHSV()

Allows loading of shader from text code string directly

Note that this version is under development and could be buggy on some
platforms...

In case graphic device could not be created it returns false instead of
failing with an error tracelog (and consequently closing the program).
Window initialization success could be checked with new function
IsWindowReady()

You can't do much with raylib if glfwInit or glfwCreateWindow fails,
currently it just exits by means of TraceLog(LOG_ERROR.
User code, however, might want to fall back to a text-only UI
or display a warning if raylib can't be used.

Added support for noise image offset

- Added: ImageAlphaClear()
- Added: ImageAlphaPremultiply()
- Reorganized some functions

- Renamed enum TextureFormat to PixelFormat for consistency
- Added support for pixel format UNCOMPRESSED_R32
- Using GetPixelDataSize() where required

Just found I need that function...

Review comments

Functionality integrated in DrawRectangle() and selectable with config
flag USE_DEFAULT_FONT_TEXTURE

I think is clearer this way...

Trace log messages could be configured with this function to select wich
ones are shown

Audio module requires a complete formatting review....

Monotonic time since InitWindow() could be retrieved with this function.

Let the user choose if using rres external library

Updated raylib version to 1.9-dev for development pourposes.

Next raylib version is planned to implement a big amount of changes, so
the version bump.

Now header is truly multiplatform...

Actually still a small pending check on XBOX gamepad controls that
hopefully will be removed with next GLFW 3.3

Support Universal Windows Platform (UWP):
- Windows 10 App
- Windows Phone
- Xbox One

- Added new function: GenImageColor()

ImageDraw() should be reviewed... specially alpha blending...

To be more generic and configurable

Added: DrawRectangleGradientV()
Added: DrawRectangleGradientH()

SetWindowTitle()
GetExtension()
