This could potentially be a breaking change, for consistency, now every possible desktop backend has the proper name assigned: GLFW, SDL, RGFW
raylib build system has been reviewed to fallback to `PLATFORM_DESKTOP_GLFW` by default when `PLATFORM_DESKTOP` defined

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

* Update raylib_api.* by CI

* Default to not use HDR, and note that HDR support requires that raylib be built with HDR enabled.

* 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.
