+============================================
+Application bugs worked around in this file:
+============================================
+
+* Various Unigine products don't use the #version and #extension GLSL
+ directives, meaning they only get GLSL 1.10 and no extensions for their
+ shaders.
+ Enabling all extensions for Unigine fixes most issues, but the GLSL version
+ is still 1.10.
+
+* Unigine Heaven 3.0 with ARB_texture_multisample uses a "ivec4 * vec4"
+ expression, which fails to compile with GLSL 1.10.
+ Adding "#version 130" fixes this.
+
+* Unigine Heaven 3.0 with ARB_shader_bit_encoding uses the uint keyword, which
+ fails to compile with GLSL 1.10.
+ Adding "#version 130" fixes this.
+
+TODO: document the other workarounds.
