Some formats are not advancing k to get pixels values

* Optimize DrawSphereEx()

Precalculates sin/cos to eliminate unnecessary calls.

* Formatting correction to previous commit

* Bugfix to optimized DrawSphereEx()

OBO error -- added 1 additional precalculated cos/sin value to each array to complete the 360-degree wraparound. Technically the value of these last elements will always be the same as the first element due to 360-degree wraparound, but this is the simplest solution.

* Corrected missing free()

* Formatting correction

* New DrawSphereEx() algorithm

* created ImageFromChannel

Adds the possibility to extract a specific channel from an image

* naming convention

* example window height

* removed threshold

* removed alpha channel

* channel example organization

* updated channel example image

* rmodels.c, LoadImageFromCgltfImage() : fix base64 padding support

This should fix the issue related to `.gltf` embeded image in base64 format, by ignoring `=` padding and calculating the data size in bytes correctly.

* follow guidelin convention

* try to follow guideline convention as much as possible

* clarify comments

i hope it's clear ennough

* Fix Makefile issues (RGFW) (linux) (macOS)

* Do not use nanosleep on windows at all (PLATFORM_DESKTOP_RGFW)

* remove #define RGFWDEF and make the #undefs only happen for their OS

* Update RGFW.h

* fix to match the RGFW updates

* remove line that shows the cursor for no reason

* Update RGFW, replace long switch with an array, update rgfw platform for RGFW

* update RGFW (fix reported glitch with drag and drop files) (linux)

* remove u16

`@This()` was naively passed to `dependencyFromBuildZig` while inside
a file that is not actually the build file, causing a panic when
actually used. Passing `@import("../build.zig")` fixes this.

It is currently impossible to check a font loaded successfully with
IsFontReady because LoadFontEx will always return a valid font.

DrawTextEx has this check:
if (font.texture.id == 0) font = GetFontDefault();  // Security check in case of not valid font

So anyone relying on the default font as a fallback for fonts failing to
load should still be covered.

* Update raylib_api.* by CI

* Fix warnings when building examples in MSVC 2022

* fix auto-format that sneaked in there.

* adding `ImageDrawLineEx` function
also review other functions for drawing lines in images

* fix `ImageDrawLineV`

* adding triangle drawing function for images

* remove unnecessary check

* fix an iteration mistake

* Initial work to correctly handle the node hierarchy in a glTF file.
Static meshes seem to work fine in my tests. Haven't tried anything
animated yet, but it's almost certainly broken.

* Fix variable naming, some comment tweaks

* Only count primitives made up of triangles in glTF meshes

* Update processing of gltf mesh animation data, to match earlier
changes to vertex/normal/tangent data

* Allow ES3 in LibraryConfigurations.cmake

* Put FULL_ES3 as linker option

* Remove =1

* Allow ES3 in LibraryConfigurations.cmake

* Put FULL_ES3 as linker option

* fix

* assert

* update

* Revert "update"

This reverts commit e8adcabd94.

* update

* remove a not stricly required flag

* [rshapes] Fix multisegment Bezier splines.

It seems to me that these functions are wrong, if you step the index by 1 you move to a control point instead of the next segment.

* Fix example shapes/shapes_splines_drawing for bezier splines.

* Draw circles to fill gaps between bezier segments.

When addRaygui is used from an external build, for example in a
bindings project, the build of a generated `raygui.c` fails with
"raylib.h not found" error from the compiler.

I've traced this down to a raylib step not adding its `src/` to the
shared list of include paths using `addIncludePath` but relying on
`addCSourceFiles` `.root` to provide the implicit include path for
raylib proper's own files.

If raygui is later added to the step the compiler won't know where
to look for `raylib.h` and friends and will fail to build.

This change simply adds raylib's `src/` to the include path list.

- The function rlGetMatrixProjectionStereo and rlGetMatrixViewOffsetStereo have RLAPI for the function declaration and cause error when compiling using RLGL_IMPLEMENTATION.

Similarly to how it's done for WAV format, by forcing the conversion
to s16 on UpdateMusicStream().

* Update raylib_api.* by CI

* make functions that take a pointer to an array take them as const pointers

* Update raylib_api.* by CI

* fix comment alignment.

Since the flag CUSTOM_CFLAGS should allow users customize things, in particular the optimization level, I figured it should come after other default ones.

Based on: "If you use multiple -O options, with or without level numbers, the last such option is the one that is effective."
