+*
+* raygui v3.0 - A simple and easy-to-use immediate-mode gui library
+*
+* DESCRIPTION:
+*
+* raygui is a tools-dev-focused immediate-mode-gui library based on raylib but also
+* available as a standalone library, as long as input and drawing functions are provided.
+*
+* Controls provided:
+*
+* # Container/separators Controls
+* - WindowBox
+* - GroupBox
+* - Line
+* - Panel
+*
+* # Basic Controls
+* - Label
+* - Button
+* - LabelButton --> Label
+* - Toggle
+* - ToggleGroup --> Toggle
+* - CheckBox
+* - ComboBox
+* - DropdownBox
+* - TextBox
+* - TextBoxMulti
+* - ValueBox --> TextBox
+* - Spinner --> Button, ValueBox
+* - Slider
+* - SliderBar --> Slider
+* - ProgressBar
+* - StatusBar
+* - ScrollBar
+* - ScrollPanel
+* - DummyRec
+* - Grid
+*
+* # Advance Controls
+* - ListView
+* - ColorPicker --> ColorPanel, ColorBarHue
+* - MessageBox --> Window, Label, Button
+* - TextInputBox --> Window, Label, TextBox, Button
+*
+* It also provides a set of functions for styling the controls based on its properties (size, color).
+*
+*
+* GUI STYLE (guiStyle):
+*
+* raygui uses a global data array for all gui style properties (allocated on data segment by default),
+* when a new style is loaded, it is loaded over the global style... but a default gui style could always be
+* recovered with GuiLoadStyleDefault() function, that overwrites the current style to the default one
+*
+* The global style array size is fixed and depends on the number of controls and properties:
+*
+* static unsigned int guiStyle[RAYGUI_MAX_CONTROLS*(RAYGUI_MAX_PROPS_BASE + RAYGUI_MAX_PROPS_EXTENDED)];
+*
+* guiStyle size is by default: 16*(16 + 8) = 384*4 = 1536 bytes = 1.5 KB
+*
+* Note that the first set of BASE properties (by default guiStyle[0..15]) belong to the generic style
+* used for all controls, when any of those base values is set, it is automatically populated to all
+* controls, so, specific control values overwriting generic style should be set after base values.
+*
+* After the first BASE set we have the EXTENDED properties (by default guiStyle[16..23]), those
+* properties are actually common to all controls and can not be overwritten individually (like BASE ones)
+* Some of those properties are: TEXT_SIZE, TEXT_SPACING, LINE_COLOR, BACKGROUND_COLOR
+*
+* Custom control properties can be defined using the EXTENDED properties for each independent control.
+*
+* TOOL: rGuiStyler is a visual tool to customize raygui style.
+*
+*
+* GUI ICONS (guiIcons):
+*
+* raygui could use a global array containing icons data (allocated on data segment by default),
+* a custom icons set could be loaded over this array using GuiLoadIcons(), but loaded icons set
+* must be same RICON_SIZE and no more than RICON_MAX_ICONS will be loaded
+*
+* Every icon is codified in binary form, using 1 bit per pixel, so, every 16x16 icon
+* requires 8 integers (16*16/32) to be stored in memory.
+*
+* When the icon is draw, actually one quad per pixel is drawn if the bit for that pixel is set.
+*
+* The global icons array size is fixed and depends on the number of icons and size:
+*
+* static unsigned int guiIcons[RICON_MAX_ICONS*RICON_DATA_ELEMENTS];
+*
+* guiIcons size is by default: 256*(16*16/32) = 2048*4 = 8192 bytes = 8 KB
+*
+* TOOL: rGuiIcons is a visual tool to customize raygui icons.
+*
+*
+* CONFIGURATION:
+*
+* #define RAYGUI_IMPLEMENTATION
+* Generates the implementation of the library into the included file.
+* If not defined, the library is in header only mode and can be included in other headers
+* or source files without problems. But only ONE file should hold the implementation.
+*
+* #define RAYGUI_STANDALONE
+* Avoid raylib.h header inclusion in this file. Data types defined on raylib are defined
+* internally in the library and input management and drawing functions must be provided by
+* the user (check library implementation for further details).
+*
+* #define RAYGUI_NO_RICONS
+* Avoid including embedded ricons data (256 icons, 16x16 pixels, 1-bit per pixel, 2KB)
+*
+* #define RAYGUI_CUSTOM_RICONS
+* Includes custom ricons.h header defining a set of custom icons,
+* this file can be generated using rGuiIcons tool
+*

+/**********************************************************************************************
+*
+* raymath v1.5 - Math functions to work with Vector2, Vector3, Matrix and Quaternions
+*
+* CONFIGURATION:
+*
+* #define RAYMATH_IMPLEMENTATION
+* Generates the implementation of the library into the included file.
+* If not defined, the library is in header only mode and can be included in other headers
+* or source files without problems. But only ONE file should hold the implementation.
+*
+* #define RAYMATH_STATIC_INLINE
+* Define static inline functions code, so #include header suffices for use.
+* This may use up lots of memory.
+*
+* CONVENTIONS:
+*
+* - Functions are always self-contained, no function use another raymath function inside,
+* required code is directly re-implemented inside
+* - Functions input parameters are always received by value (2 unavoidable exceptions)
+* - Functions use always a "result" anmed variable for return
+* - Functions are always defined inline
+* - Angles are always in radians (DEG2RAD/RAD2DEG macros provided for convenience)

+*
+* rlgl v4.0 - A multi-OpenGL abstraction layer with an immediate-mode style API
+*
+* An abstraction layer for multiple OpenGL versions (1.1, 2.1, 3.3 Core, 4.3 Core, ES 2.0)
+* that provides a pseudo-OpenGL 1.1 immediate-mode style API (rlVertex, rlTranslate, rlRotate...)
+*
+* When chosing an OpenGL backend different than OpenGL 1.1, some internal buffer are
+* initialized on rlglInit() to accumulate vertex data.
+*
+* When an internal state change is required all the stored vertex data is renderer in batch,
+* additioanlly, rlDrawRenderBatchActive() could be called to force flushing of the batch.
+*
+* Some additional resources are also loaded for convenience, here the complete list:
+* - Default batch (RLGL.defaultBatch): RenderBatch system to accumulate vertex data
+* - Default texture (RLGL.defaultTextureId): 1x1 white pixel R8G8B8A8
+* - Default shader (RLGL.State.defaultShaderId, RLGL.State.defaultShaderLocs)
+*
+* Internal buffer (and additional resources) must be manually unloaded calling rlglClose().
+*
+*
+* CONFIGURATION:
+*
+* #define GRAPHICS_API_OPENGL_11
+* #define GRAPHICS_API_OPENGL_21
+* #define GRAPHICS_API_OPENGL_33
+* #define GRAPHICS_API_OPENGL_43
+* #define GRAPHICS_API_OPENGL_ES2
+* Use selected OpenGL graphics backend, should be supported by platform
+* Those preprocessor defines are only used on rlgl module, if OpenGL version is
+* required by any other module, use rlGetVersion() to check it
+*
+* #define RLGL_IMPLEMENTATION
+* Generates the implementation of the library into the included file.
+* If not defined, the library is in header only mode and can be included in other headers
+* or source files without problems. But only ONE file should hold the implementation.
+*
+* #define RLGL_RENDER_TEXTURES_HINT
+* Enable framebuffer objects (fbo) support (enabled by default)
+* Some GPUs could not support them despite the OpenGL version
+*
+* #define RLGL_SHOW_GL_DETAILS_INFO
+* Show OpenGL extensions and capabilities detailed logs on init
+*
+* #define RLGL_ENABLE_OPENGL_DEBUG_CONTEXT
+* Enable debug context (only available on OpenGL 4.3)
+*
+* rlgl capabilities could be customized just defining some internal
+* values before library inclusion (default values listed):
+*
+* #define RL_DEFAULT_BATCH_BUFFER_ELEMENTS 8192 // Default internal render batch elements limits
+* #define RL_DEFAULT_BATCH_BUFFERS 1 // Default number of batch buffers (multi-buffering)
+* #define RL_DEFAULT_BATCH_DRAWCALLS 256 // Default number of batch draw calls (by state changes: mode, texture)
+* #define RL_DEFAULT_BATCH_MAX_TEXTURE_UNITS 4 // Maximum number of textures units that can be activated on batch drawing (SetShaderValueTexture())
+*
+* #define RL_MAX_MATRIX_STACK_SIZE 32 // Maximum size of internal Matrix stack
+* #define RL_MAX_SHADER_LOCATIONS 32 // Maximum number of shader locations supported
+* #define RL_CULL_DISTANCE_NEAR 0.01 // Default projection matrix near cull distance
+* #define RL_CULL_DISTANCE_FAR 1000.0 // Default projection matrix far cull distance
+*
+* When loading a shader, the following vertex attribute and uniform
+* location names are tried to be set automatically:
+*
+* #define RL_DEFAULT_SHADER_ATTRIB_NAME_POSITION "vertexPosition" // Binded by default to shader location: 0
+* #define RL_DEFAULT_SHADER_ATTRIB_NAME_TEXCOORD "vertexTexCoord" // Binded by default to shader location: 1
+* #define RL_DEFAULT_SHADER_ATTRIB_NAME_NORMAL "vertexNormal" // Binded by default to shader location: 2
+* #define RL_DEFAULT_SHADER_ATTRIB_NAME_COLOR "vertexColor" // Binded by default to shader location: 3
+* #define RL_DEFAULT_SHADER_ATTRIB_NAME_TANGENT "vertexTangent" // Binded by default to shader location: 4
+* #define RL_DEFAULT_SHADER_ATTRIB_NAME_TEXCOORD2 "vertexTexCoord2" // Binded by default to shader location: 5
+* #define RL_DEFAULT_SHADER_UNIFORM_NAME_MVP "mvp" // model-view-projection matrix
+* #define RL_DEFAULT_SHADER_UNIFORM_NAME_VIEW "matView" // view matrix
+* #define RL_DEFAULT_SHADER_UNIFORM_NAME_PROJECTION "matProjection" // projection matrix
+* #define RL_DEFAULT_SHADER_UNIFORM_NAME_MODEL "matModel" // model matrix
+* #define RL_DEFAULT_SHADER_UNIFORM_NAME_NORMAL "matNormal" // normal matrix (transpose(inverse(matModelView))
+* #define RL_DEFAULT_SHADER_UNIFORM_NAME_COLOR "colDiffuse" // color diffuse (base tint color, multiplied by texture color)
+* #define RL_DEFAULT_SHADER_SAMPLER2D_NAME_TEXTURE0 "texture0" // texture0 (texture slot active 0)
+* #define RL_DEFAULT_SHADER_SAMPLER2D_NAME_TEXTURE1 "texture1" // texture1 (texture slot active 1)
+* #define RL_DEFAULT_SHADER_SAMPLER2D_NAME_TEXTURE2 "texture2" // texture2 (texture slot active 2)
