Win64, LCL, simple shapes - something got broken

The “ideal” fix is to instead have EnableFixedFunction=false, BuggyPureShaderPipeline=false, and allow all the shader code to just run on your GPU (as it does on any other GPU).

We’ve done a few fixes for ATI GPUs lately, and this is done.

The BuggyPureShaderPipeline property is now completely removed (it is never buggy now ), rendering on older ATI cards is now both more reliable and consistent with what happens on more modern GPUs (ATI or not ATI).
