This use of offset 'i' should follow the range check.

* Add WASM support for Zig build

* Improve Web example building

* Remove emscript example building with Zig again

* Readd windows emscripten variables

fixing typo

This simplification will allow the usage of `rshapes` as STANDALONE mode in a future. Only a small set of `rlgl` functions are required and they can be "more" easely replaced if no `rlPushMatrix()`/`rlPopMatrix()` are involved.

More simplification planned for the future, maybe the textures dependencies.

* Start 2d lights example.

* finish example

* update image.

* Cleanup render textures

* Fixes to handle shadows on edges that are near to the light better.

* tabs

* move to shapes

This function was renamed for consistency in raylib 3.0, just unified all examples to use TextFormat() instead of FormatText()

Redesigns, deletes and renames

Also noted authors propertly on contributed examples

Variable operations inside the functions should be evaluated before the function operations.

Some examples included in this batch require the included libraries: `easings.h` and `raygui.h`. Examples included:

 - shapes_bouncing_ball
 - shapes_collision_area
 - shapes_following_eyes
 - shapes_draw_circle_sector (requires raygui.h)
 - shapes_draw_rectangle_rounded (requires raygui.h)
 - shapes_draw_ring (requires raygui.h)
 - shapes_easings_ball_anim (requires easings.h)
 - shapes_easings_box_anim (requires easings.h)
 - shapes_easings_rectangle_array (requires easings.h)

Added a bunch of useful text management functions.
Consequently, some already available functions like `FormatText()` and `SubText()` has been renamed for consistency. Created temporal fallbacks for old names.
raylib version bumped to 2.3.
