Shaders Awesome Shaders (Advanced)

I have converted 4 of Martijn Steinrucken aka BigWings beautiful shaders for gamemaker
To show the potential

They have a sharealike creative common licence and you need to contact the author before using them in a commercial product
I suggest watching his youtube tutorial for the drive home, great learning experience

ill try to explain a little about the conversion
You should understand shaders and how uv's work, to center and scale them, alot of shadertoys shaders you may have to flip the y of the uv
uv.y = -uv.y moving a uv can be done with uv += .5 or uv.x -= somevalue, scaleing is done with uv *= 2.; (smaller) uv/= 2.; (larger)
and use gamemakers syntax like gl_fragcoord, when you see uv=iresoulution.x/iresolution.y; you can substitue it for uv=v_vTexcoord;
also Gamemaker uses gm_basetexture which is the objects sprite (basically ichannel0) doing stuff like the "Bokeh" effect
are done using the uv coordinates but not the texture. So if you understand that before watching the tutorial it helps alot as it involves
some pretty serious math

HeartFelt shader is almost working, just got to tweak the smoothstep a bit
