Terrain example

[VinnyVicious]

A terrain example would be nice to have.

Purpose of examples in bgfx is to show of API use + to cover different feature code paths. Not sure how terrain fits into this. Is there anything specific that's unclear about API and how to do with bgfx?

A sort of terrain example might be useful for testing dynamic vertex buffer updates, and testing texture sampling in vertex shaders. I'm thinking a simple heightmap based terrain with raise/lower (right/left click?) with three options available in a menu:

1. Regular Vertex Buffer: destroy/create for each height update.
2. Dynamic Vertex Buffer: update for each height update.
3. Vertex Shader Texture Sampling: the height data is written to a texture and sampled in the vertex shader.

I might have time this weekend to throw it together if there is interest.

Sounds good! 👍

Also it might be enough just to cover 2 and 3.
