...mostly done with a rewriting Clang plugin, with just some manual tweaking necessary to fix poor macro usage. Change-Id: I71fa20213e86be10de332ece0aa273239df7b61a

This primitive is specialized to Grid visualisation. The graphic definition
|
|
(Transform) contains the whole grid area, but will of course be combined
|
|
with the visible area (Viewport) when decomposed. Also a reolution-dependent
|
|
point reduction is used to not create too much grid visualisation data. This
|
|
makes this primitive highly view-dependent and it dynamically buffers
|
|
the last decomposition dependent from the Viewport used.
