Stackage release

Hopefully I'll be able to get this version into Stackage

Hackage build fixes

In the desperate effort to get it to Hackage, I did some small changes to the cabal file. Let's see if that helps.

Updated base upper version for Hackage

This is just a small fix that adds upper bound to the base library. Thanks to that, Hate is now on Hackage!

Added spritePart function

This small function is essential for supporting bitmap font rendering. In fact, a prototype of such can already be seen here.

Added solid colors

Added "colored" combinator and fixed solid color pipeline

OpenGL 3.3 support with swappable backends

Rejoice! Hate now has not one, but two separate backends (sharing some code) that either use the full power of modern 4.4+ OpenGL, or strive to provide a compatibility layer on 3.3. This means older Mac OS PCs should now be able to run it.

Added error reporting for window creation

Failure in window creation or GLFW initialization will now output to console.

Added support for other image types

Thanks to JuicyPixels-util, JPG images should now work. Every loaded image will be converted to RGBA from now on.

This release also introduces an upper cap for GLFW-b, because 1.4.7 appears broken on Windows, as pointed out by @kBoK.

Window projection recalculation

Hate now reacts properly to window sizing event. Note that (0,0) coordinates are now in top-left corner.

Fix: added Origin Reference parameter to spritesheet rendering

spriteSheet changed from

spriteSheet :: Int -> SpriteSheet -> DrawRequest

to

spriteSheet :: OriginReference -> Int -> SpriteSheet -> DrawRequest
