Develop
=======
Change
------
Platform GL headers are no longer included in juce_opengl.h
Possible Issues
---------------
Projects depending on symbols declared in these headers may fail to build.
Workaround
----------
The old platform-supplied headers have been replaced with a new juce_gl.h
header which is generated using the XML registry files supplied by Khronos.
This custom header declares GL symbols in the juce::gl namespace. If your code
only needs to be JUCE-compatible, you can explicitly qualify each name with
`juce::gl::`. If you need your code to build with different extension-loader
libraries (GLEW, GL3W etc.) you can make all GL symbols visible without
additional qualification with `using namespace juce::gl`.
Rationale
---------
Using our own GL headers allows us to generate platform-independent headers
which include symbols for all specified OpenGL versions and extensions. Note
that although the function signatures exist, they may not resolve to a function
at runtime. If your code uses commands from an extension or recent GL version,
you should check each function pointer against `nullptr` before attempting to
use it. To avoid repeatedly checking, you could query a subset of functions
after calling gl::loadFunctions() and cache the results. Supplying custom GL
headers also allows us to use C++ techniques (namespaces, references), making
the headers safer than the platform-defined headers. Platform headers are
generally written in C, and export a significant portion of their symbols as
preprocessor definitions.
Change
------
The functions `getComponentAsyncLayerBackedViewDisabled`

/** This class contains a generated list of OpenGL extension functions, which are either dynamically loaded
for a specific GL context, or simply call-through to the appropriate OS function where available.
This class is provided for backwards compatibility. In new code, you should prefer to use
functions from the juce::gl namespace. By importing all these symbols with
`using namespace ::juce::gl;`, all GL enumerations and functions will be made available at
global scope. This may be helpful if you need to write code with C source compatibility, or
which is compatible with a different extension-loading library.
All the normal guidance about `using namespace` should still apply - don't do this in a header,
or at all if you can possibly avoid it!

/* Khronos platform-specific types and definitions.
*
* The master copy of khrplatform.h is maintained in the Khronos EGL
* Registry repository at https://github.com/KhronosGroup/EGL-Registry
* The last semantic modification to khrplatform.h was at commit ID:
* 67a3e0864c2d75ea5287b9f3d2eb74a745936692
*
* Adopters may modify this file to suit their platform. Adopters are
* encouraged to submit platform specific modifications to the Khronos
* group so that they can be included in future versions of this file.
* Please submit changes by filing pull requests or issues on
* the EGL Registry repository linked above.
*
*
* See the Implementer's Guidelines for information about where this file
* should be located on your system and for more details of its use:
* http://www.khronos.org/registry/implementers_guide.pdf
*
* This file should be included as
* #include <KHR/khrplatform.h>
* by Khronos client API header files that use its types and defines.
*
* The types in khrplatform.h should only be used to define API-specific types.
*
* Types defined in khrplatform.h:
* khronos_int8_t signed 8 bit
* khronos_uint8_t unsigned 8 bit
* khronos_int16_t signed 16 bit
* khronos_uint16_t unsigned 16 bit
* khronos_int32_t signed 32 bit
* khronos_uint32_t unsigned 32 bit
* khronos_int64_t signed 64 bit
* khronos_uint64_t unsigned 64 bit
* khronos_intptr_t signed same number of bits as a pointer
* khronos_uintptr_t unsigned same number of bits as a pointer
* khronos_ssize_t signed size
* khronos_usize_t unsigned size
* khronos_float_t signed 32 bit floating point
* khronos_time_ns_t unsigned 64 bit time in nanoseconds
* khronos_utime_nanoseconds_t unsigned time interval or absolute time in
* nanoseconds
* khronos_stime_nanoseconds_t signed time interval in nanoseconds
* khronos_boolean_enum_t enumerated boolean type. This should
* only be used as a base type when a client API's boolean type is
* an enum. Client APIs which use an integer or other type for
* booleans cannot use this as the base type for their boolean.
*
* Tokens defined in khrplatform.h:
*
* KHRONOS_FALSE, KHRONOS_TRUE Enumerated boolean false/true values.
*
* KHRONOS_SUPPORT_INT64 is 1 if 64 bit integers are supported; otherwise 0.
* KHRONOS_SUPPORT_FLOAT is 1 if floats are supported; otherwise 0.
*
* Calling convention macros defined in this file:
* KHRONOS_APICALL
* KHRONOS_APIENTRY
* KHRONOS_APIATTRIBUTES
*
* These may be used in function prototypes as:
*
* KHRONOS_APICALL void KHRONOS_APIENTRY funcname(
* int arg1,
* int arg2) KHRONOS_APIATTRIBUTES;
