Alex Szpakowski ff8358a979 Removed void effects(…) pixel shader prototype. Added void effect(). Allows calling love.graphics.draw with textures of different types with a custom shader without having an extra sampler2D.
effect() takes no arguments and returns nothing, you are responsible for assigning a value to either love_PixelColor or love_Canvases[n] in the function. You can declare ‘MainTex’, which will be whatever texture is used with any Drawable drawn with love.graphics.draw. You can also declare ‘VaryingColor’ and ‘VaryingTexCoord’, which are passed down from the vertex shader by love automatically. love_PixelCoord is also available.

Alex Szpakowski 73fd45558b Implement Array, Cubemap, and Volume texture types (issue #1111).
- Add love.graphics.newArrayImage, newCubeImage, and newVolumeImage.
- Add love.graphics.newCanvas(w, h, layers) and newCanvas(w, h, layers, settings). Add ‘type’ field to the settings table of newCanvas.

- Add new love.graphics.setCanvas variants: setCanvas(canvas, slice), and setCanvas(canvastable) where canvastable is in the format: {{canvas1, layer=2}, {canvas2, face=5}}

- Add Texture:getTextureType, getDepth, getLayerCount, getMipmapCount, and getFormat.

- Remove Image:getData and Image:refresh.
- Add Image:replacePixels(imagedata [, slice] [, mipmap]).

- Update Canvas:newImageData to accept a slice argument.

- Add love.image.newCubeFaces(imagedata).

Alex Szpakowski 731b5d5cf0 Added support for GLSL 3 shaders (GLSL 3.30 and GLSL ES 3.00).
To use GLSL 3 in a shader, the first line of the shader has to be: #pragma language glsl3

glsl1 is the default language.

Added “glsl3” graphics feature as part of the table returned by love.graphics.getSupported().

Added love.graphics.validateShader(boolean gles, shadercode). It returns a boolean along with an error string if the shader code has errors for its target language and platform (gles or desktop).

Implemented support for Core Profile OpenGL 3.3 in love.graphics.

Alex Szpakowski 8899c03651 Add C++ side support for unsigned int shader uniforms. Note that the shader languages love currently supports (glsl 1.20, glsl es 1.00) don’t support uints at the moment.
