Changed vertex shader callback function name from 'transform' to 'position', added more vertex shader defines (some to make it easier to eventually have a GLES2 backend), hopefully updated Visual Studio project with changed filenames

Bind texture id 0 (no texture) instead of disabling/re-enabling texturing entirely, when drawing graphics primitives. This both allows shaders to potentially use their own textures when drawing textureless primitives, and reduces overhead caused by constant GL state changes when drawing many graphics primitives.

reduced unnecessary usage of glUseProgram, shadereffect is now properly detached in unloadVolatile and reattached if necessary in loadVolatile, made current and max texture units static to prevent different shaders from overwriting the value of different texture units

VertexBuffer/SpriteBatch speed tweaks.
...
- VertexBuffer holds permanent copy of the vertex data and is only read from
GPU memory was written outside a sb:bind()/sb:unbind() pair.
- "Orphan" the current GPU buffer on unmap() before uploading the changed data
to the GPU to avoid implicit synchronisation lags.

Fix Issue #476 : Add HDR Canvas (thanks, Alexander Szpakowski!).
...
* Add `love.graphics.isSupported("hdrcanvas")' to query whether the hardware
actually supports HDR canvases.
* Add optional third argument to `love.graphics.newCanvas(w,h, type)', where
`type' is one of "normal" or "hdr" and defaults to "normal". HDR canvases
use floating point that can have values > 1 to store pixels, allowing for
HDR rendering and other higher level lighting techniques when combined with
pixel effects.
* Add `canvas:getType()'.

Fix issue #437 : Area-based particle spawn.
...
New particles are spawned around the particle emitter position according to a
configurabe distribution.
New functionality:
particlesystem:setAreaSpread(distributon, x, y)
distribution, x, y = particlesystem:getAreaSpread()
Where `distribution' is one of "none", "uniform", "normal".
`x' and `y' take different meaning based on the distribution:
* none: no area spread - particles spawned at emitter position.
* uniform: particle spawned at px,py in the rectangle around emitter
position ex,ey, i.e.:
ex - x < px < ex + x, ey - y < py < ey + y,
* normal: particle position drawn from a normal/gaussian distribution
with mean ex,ey and standard deviation x,y, i.e.:
px \in N(ex, x²), py \in N(ey, y²).

Fix #435 (for real this time). Unfixes #324 .
...
Add a extern vec2 love_ScreenSize to the pixel effects that will
be (re)set upon PixelEffect::loadVolatile() and is used to flip
the fragment coordinate.
Unfixes #324 because canvases can have different dimensions than
the screen.
