[Crystal-develop] g2dtest progress

[Ralph Campbell]

I was trying to find out why the g2dtest LineClipTest() and
BoxClipTest() weren't displaying anything.
When I added a printf() in libs/csplugincommon/opengl/glcommon2d.cpp
DrawLine(), I started to see lines being drawn.
I suspect there is some issue with drawing commands being buffered and
not flushed to the display per frame so that nothing is seen unless
there is a delay.
Perhaps this is enough of a hint to find the problem.

Could you try adding the following to the end of
G2DTestSystemDriver::StateFrame:
myG3D->FinishDraw();

It seems that g2dtest only starts the drawing but never signals
iGraphics3D that it's done which can cause some issues and mess up the
page swapping, etc.

I checked in the change you suggested.
It didn't seem to make any difference though.
