2015-09-10: initial early-preview release
2015-09-15: RiceScript: added OpenGL-like matrix operations for GLSL matrix types: identity, translate, rotate, scale
2015-09-16: RiceScript: added casting constructors vec2(vec3) and vec3(vec4)
2015-09-29: RiceScript: fixed vec4(vec2,double,double), vec4(double,vec2,double), vec4(double,double,vec2) constructors
2015-10-14: RiceScript: added matrix inverse operations for glsl_math
2015-10-14: added consolef and precision setting %.Dg (D = number of fractional digits) for consolef/printf
2015-10-26: fixed mipmapping for glCapture (power of two textures only), added GL_TRIANGLE_STRIP primitive
2015-10-27: removed GL_MIN/GL_MAX as it is not supported by WebGL 1.0, added glColorMask, glDepthMask and glDepthFunc
2015-11-02: RiceScript: fixed normalize in glsl translation
2015-11-02: added thumbnail saving, fixed context reuse/cleanup in preview window,  #option preserve_buffer is 1 by default
2015-11-08: RiceScript: fixed scalar*vector operations, fixed boolean and conditional a?b:c expressions
2015-11-08: fixed glBlendFunc bug (run-time exception), fixed glCaptureEnd bug (flushing mesh batches)
2015-11-15: RiceScript: glsl_math: access to matrix components, "float" type, new functions: reflect and component-wise floor, ceil and fract
2015-11-15: fixed line numbers in error messages for shaders with #use macro
2015-11-21: enabled EXT_frag_depth, updated "Implicit spheres" and "Implicit capsules" examples
2015-11-22: added glViewport, glScissor/GL_SCISSOR_TEST and glDepthRange
2015-11-22: RiceScript: added double(int) and float(int) casting
2015-12-26: modified "hide editor" behaviour (full window only in fullscreen browsing)
2016-01-02: RiceScript: fixed GLSL translation of numerical constants, auto including enum's for #use macro
2016-01-12: KGL_* syntax is obsolete: GL_LINEAR = KGL_LINEAR, GL_NEAREST = KGL_NEAREST, GL_CLAMP = KGL_CLAMP, GL_REPEAT = KGL_REPEAT
2016-01-12: added 16bit and 32bit texture and render buffer formats: GL_RGB, GL_RGBA, GL_UNSIGNED_BYTE, GL_HALF_FLOAT, GL_FLOAT

2016-01-16: added missing letter key codes from KEY_A to KEY_Z
2016-01-17: default format type for textures is GL_RGBA (KGL_BGRA32 is obsolete, rgba(,,,) function is now packing in a proper R8G8B8A8 order)
2016-01-17: fixed GL_HALF_FLOAT array input for glSetTex
2016-01-17: fixed glBlendEquation, added GL_MIN and GL_MAX
