FixedFuncPipeline GL_POINTS: Fix gl_PointSize (attribute data format), Add GL_POINT_SOFT and dist/fade attenuation (Adding basic POINT unit tests)

gl_PointSize (and all other uniform array elems) was not propagated due to wrong usage of GLUniformData component param.
Due to efficiency, we use vec4[2] now and #defines in shader to easy readability.

GL_POINT_SOFT uses gl_PointCoord to determnine inside/outside circle position
while adding a seam of 10% in/out. This almost matches 'other' implementations and gives a nice smooth circle.

!GL_POINT_SOFT produces a proper square (billboard).

Point-Vertex shader takes dist/fade attentuation into account.
