Ryan C. Gordon ed10d9473f opengl: Build out full GL_LINES and respect the diamond-exit rule.
Likewise for the GLES1 and GLES2 renderers.

This solves the missing pixel at the end of a line and removes all the
heuristics for various platforms/drivers. It's possible we could still use
GL_LINE_STRIP with this and save some vertex buffer space, assuming this
doesn't upset some driver somewhere, but this seems to be a clean fix that
makes the GL renderers match the software renderer output.

Diamond-exit rule explanation:

Fixes Bugzilla #3182.
