+ * 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.

+ @file pugl_gl3_demo.c An example of drawing with OpenGL 3.
+
+ This is an example of using OpenGL for pixel-perfect 2D drawing. It uses
+ pixel coordinates for positions and sizes so that things work roughly like a
+ typical 2D graphics API.
+
+ The program draws a bunch of rectangles with borders, using instancing.
+ Each rectangle has origin, size, and fill color attributes, which are shared
+ for all four vertices. On each frame, a single buffer with all the
+ rectangle data is sent to the GPU, and everything is drawn with a single
+ draw call.
+
+ This is not particularly realistic or optimal, but serves as a decent rough
+ benchmark for how much simple geometry you can draw. The number of
+ rectangles can be given on the command line. For reference, it begins to
+ struggle to maintain 60 FPS on my machine (1950x + Vega64) with more than
+ about 100000 rectangles.
