* Add gather feature example

* Add Arrow, Coordinate System and Table S2H examples

* Add generate user font s2h example

* Add 2D s2h example

* Add 3D s2h example

* Add clear s2h example

* Add Quad Post s2h example

* Add Use User Font s2h example

* Add Debug Zoom s2h example

* Add Zoom 2D s2h example

* Update s2h samples order to corespong to GiGi one

Enhance Gather sample to looks more like the original one

* Handle bottom-left fragment origins in S2H shaders

* Fix S2H rendering across OpenGL, Vulkan, and DX12

* Removed the redundant u_s2hScreen uniform

- S2H now derives the top-left pixel coordinate from bgfx’s u_viewRect and OpenGL’s built-in bgfx_ndc.z
- Removed its creation, per-view uploads, and destruction from s2h.cpp

* Update 54-s2h shaders to match bgfx shader style

`float2/3/4` → `vec2/3/4`
`float4x4` → `mat4`
`int2 / uint2` → `ivec2 / uvec2`
