Use vertex shader for surface graph To enhance the update performance, surface graph starts using vertex shader Pick-to: 6.6 Task-number: QTBUG-108129 Change-Id: I0002c7babe27bf11292404315b692fad56949c91 Reviewed-by: Tomi Korpipää <tomi.korpipaa@qt.io> 2023-05-05 10:51:27 +00:00			`void MAIN()`

Fix massive data test crash The initial created mesh is limited to the 4k texture size. The amount of vertices modified now depends on the sampleSpace (ranges) and only that amount of vertices is written into the height texture.
