[SailfishDevel] ShaderEffect QML element

[Luca Donaggio]

I replied myself:

the problem was with this syntax in my fragment shader code:

vec2(-0.75f, -0.5f)

it's legal inside the emulator but *not on real device*.

Of course, all it takes to make it work is using float() constructor:

vec2(float(-0.75), float(-0.5))

Hope it could help someone else.
