[examples] List of examples not working properly on Web platform

[raysan5]

This issue is intended to get feedback for examples not working properly. Please, answer to this issue with the examples not working properly and the unexpected behaviour detected. Thanks!

Name	Runs	Fixed	Comments
core_loading_tread	❌		Example crashes, it requires multi-threading support on raylib compilation before linkage
core_window_letterbox	✔️		Canvas resizing issue
core_top_down_lights	✔️		Minor: F1 shortcut conflicts with browser
textures_blend_modes	✔️		Quite poor example, requires a redesign
textures_draw_tiled	✔️		Canvas resizing issue
models_bone_socket	✔️		Minor: Slow rotation speed
models_point_rendering	✔️	⚠️	Points not drawn, drawing triangles instead. OpenGL ES 2.0 does not support point-mode drawing
models_yaw_pitch_roll	✔️		OBJ issues with texture coordinates loading
models_skybox	✔️		Skybox not drawn
shaders_raymarching	✔️		Canvas resizing issue
shaders_texture_tiling	✔️	⚠️	Shader compilation issues. OpenGL ES 2.0 does not support texture-repeat wrap mode
shaders_julia_set	✔️	✔️	Shader compilation issues
shaders_mesh_instancing	✔️	✔️	Shader loading: works locally, some server issue on shader loading (skipped characters) -> Issue seems related to CRLF vs LF line-break changes on .data file not aligned with expected size defined in .js. Building and uploading the example on Linux fixes it.
shaders_spotlight	✔️		Minor: Too fast movement
shaders_hybrid_render	✔️		Shader loading: works locally, some server issue on shader loading (skipped characters)
shaders_deferred_render	❌		Shader loading, not ported to GLSL100...
shaders_vertex_displacement	✔️		Shader loading: works locally, some server issue on shader loading (skipped characters)

Issue with shaders loading seems it could be related to not properly reading line-breaks and considering them as 2 bytes instead of just one and then something is mangled, really weird issue, it requires investigation...

Also detected some issues with the inputs related to the web requirement of clicking over the canvas to "enable" input access... that behaviour should probably be reviewed but it's a web-design-related.

Vertex Displacement doesn't seem to work for me

Mesh Instancing example doesn't seem to work as well.

Deferred render, Julia set and Texture tiling failed to compile the shader. Hybrid Rendering failed to compile the rasterizing shader.

Custom frame control not responding to keyboard input. Pressing Space Bar doesn't pause the animation and using the arrow keys doesn't make it faster or slower. Tested it in chrome, firefox nightly, regular firefox, and also Opera GX.

Also skybox only displays this black background in all mentioned browsers

@treblig-punisher thanks for reporting, custom frame control requires a special raylib build (SUPPORT_CUSTOM_FRAME_CONTROL flag enabled) so it's expected not working on web.

models_skybox is already on above list.
