Change 63e6c9ada82dc8f16e705cef5f89292784b7ace4 introduced snapping to
the pixel grid in the vertex shader for native text, but this code was
broken on retina displays because it assumed integer only positions.
Fix it by including the retina scale factor into the rounding.

The implementation relied on the full matrix, but did not
set the RequiresFullMatrix flag. Setting the flag would
have serious negative performance impact as it prevents
batching, so we solve it in the vertex shader instead.

The default implementation of QSGShaderMaterial::vertexShader() and
fragmentShader() now loads the GLSL source from a list of source files
that can be specified via the setShaderSourceFile() or
setShaderSourceFiles() functions.
Multiple shader source files for each shader stage are supported. Each
source file will be read in the order specified and concatenated
together before being compiled.
The other places where Qt Quick 2 loads shader source code have
been adapted to use the new QSGShaderSourceBuilder, which is also
used internally by QSGMaterial.
This puts Qt Quick 2 into a better state ready to support OpenGL
core profile and to load different shaders based upon OpenGL version,
profile, GPU vendor, platform, etc.
