* review the loading and management of textures
to be closer to the OpenGL API
* texture sampling optimization
* review get pixel functions
+ review unorm/float conversion
* add several buffer format support
Several depth and color formats have been added for the framebuffer.
8-bit, 16-bit, and 24-bit formats are now available for depth.
RGB 8-bit (332), RGB 16-bit (565), and RGB 24-bit (888) formats are now available for color.
Alpha support is no longer present for the framebuffer at the moment, but it can easily be restored by adding the formats and reinterpolating the alpha in the areas that do not perform color blending.
Additionally, this commit brings performance improvements.
* tweaks
* impl line width
* impl points + point size
* fix and improve polygon clipping functions
* impl polygone modes
* add some not planned functions
- `glDepthMask`
- `glColorMask`
* framebuffer resizing + handle init failure
* add quick notes about line clipping algorithms used
* start to impl scissor test + review line clipping
The support for the scissor test has been implemented for clearing as well as for triangle clipping.
The implementation for lines and points is still missing.
I also removed the 2D clipping of lines that used the Cohen-Sutherland algorithm, opting instead to always use the Liang-Barsky algorithm in all cases.
This simplifies the implementation, and the 2D version would have caused issues when interpolating vertices in the future if we want to implement additional features.

This file seems to not do anything useful. From what I can tell the
OSX_FATLIB option sets CMAKE_OSX_ARCHITECTURES to "x86_64;i386". This
doesn't account for the arm that apple now has, as well as 32 bit
support being completely removed, and I think it's entirely reasonable
to expect users to pass the necessary architectures they want
themselves. It's possible this could break some users who rely on this,
but I sincerely doubt anyone does. The solution is trivial either way
(put -DCMAKE_OSX_ARCHITECTURES="i386;x86_64" on the command line
yourself)
The second part of BuildOptions.cmake claims to set PLATFORM to "Web" if
the emscripten toolchain file is used (if (EMSCRIPTEN)), but it does not
work correctly anyway. Currently, glfw searches for wayland and x11
libraries and fails likeso:
CMake Error at /usr/share/cmake/Modules/FindPkgConfig.cmake:645 (message):
The following required packages were not found:
- wayland-client>=0.2.7
- wayland-cursor>=0.2.7
- wayland-egl>=0.2.7
- xkbcommon>=0.5.0
Call Stack (most recent call first):
/usr/share/cmake/Modules/FindPkgConfig.cmake:873 (_pkg_check_modules_internal)
src/external/glfw/src/CMakeLists.txt:163 (pkg_check_modules)
Considering this code doesn't work as described, it's okay to delete it.
I think a better check should be implemented, but that is for a
different PR.

Support creating a 3x3 pixels white rectangle at the bottom-right corner of the generated font atlas image, useful for shapes+text drawing in a single draw call!
Those functions were platform dependent and user has no control over the file created. They have been removed from raylib and just moved to `core_storage_values` example.
Allow to choose which modules are compiled with raylib, if some modules are excluded from compilation, required functionality is not available but smaller builds are possible.
raylib modules have been slightly renamed to add some identity and note that they are independent modules that can be used as standalone separate parts of raylib if required.
The renamed modules are:
- `core` -> `rcore`
- `shapes` -> `rshapes`
- `textures` -> `rtextures`
- `text` -> `rtext`
- `models` -> `rmodels`
- `camera` -> `rcamera`
- `gestures` -> `rgestures`
- `core` -> `rcore`
All the build systems has been adapted to this change.
CMake relied on this file for configurations and also was interfering in the regular config.h by having a separate definition if building with CMake. This was not entirely correct so instead we will define compile time definitions separately through CMake (CompileDefinitions.cmake) and also will use the provided EXTERNAL_CONFIG_FLAGS that I found that will not use config.h in through the build process.
I also introduced a new compiler option (CUSTOMIZE_BUILD) that when OFF will use the default config.h and when ON will show other options for redefining your own options.
Fixed an error in rlgl.h where if you have both RLGL_STANDALONE and SUPPORT_VR_SIMULATOR you get a compile time error.
As described in the official documentation https://cmake.org/cmake/help/v3.0/variable/BUILD_SHARED_LIBS.html this flag is global by default and controls if the library will be built as a shared or a static library allowing us to define only one call to the add_library function (without specifying its type). It is also added as an option to be visible in CMake GUI applications.
* Delete emscripten.cmake
This file is not needed at this point. EMSDK provides a toolchain file that has a lot more things in it and is better supported. Project currently works fine with the documentation provided in Emscripten SDK on how to build projects.
* First pass file separation.
The main two files are cleaner now. Only important things can be seen. Major changes include:
- raylib_static is now the alias instead of raylib
- Repeating segments are removed and pulled into separate files into <root>/cmake
- File is reordered to make more sense
- Installs are better structured
- Library is build into an output directory "raylib" instead of "src"
- All public header files are now set as a public header file
- Source files need to be listed (it is a bad practice to capture them using wildcards and file globs)
- CMakeLists are better commented
* Second pass on the example dirs.
They are quite complex so I'm more hesitant to do major changes. Also it works pretty well. Noticed that I forgot one of the seperated files and added it into src/CMakeLists.txt.
* Returned the header copy as it was convenient to have the public headers copied.
* A better description to the variable RAYLIB_IS_MAIN
