e602d25f09 Removed strcpy that copied to itself. 
Found by running glslang with -fsanitize=address in clang.
Also fixes a potential buffer-overrun with return from lReadByte.

3ac051e41d SPV: recursively propagate row/col majorness through nested structures. 
This includes doing structure uniqueness modulo majorness, for shared nested structures.

61c47a951b Constant folding: Correct result type of non-square matrix folding. 
This also made the function easier to read by identifying
left and right operands more clearly.

es version and core profile.

61d9fb9048 Semantics: 'invocations' defaults to 1, not 0. 
'invocations' was using 0 as the "shader never set" flag and as the
default. Formalize this and explicit set to 1 and link time.

494a02a2b0 Semantics: Geometry stage can support max_vertices = 0. 
To do this, more generally use a named -1 as a not set value.

989df85dcd Array-sizing bug fix: multiple array initializers of different size in the same declaration. 
Handles the case of
    float[] x = float[] (1.0, 2.0, 3.0),
            y = float[] (1.0, 2.0, 3.0, 4.0);
where a shallow copy of the type arrayness from the left-most float[]
was getting used twice.

876a0e392e Add an osinclude.h below each OS directory, redirects by platform macro 
* Linux folder has been renamed to Unix, to match defines and so that it
  compiles on OS X.
* This removes the need for a per-platform include search path for the
  right OS folder

6998987ecf Avoid costly indirect calls of tStringInput::(un)?getch through TPpContext 
There is no calls to the TPpContext that could change the current input,
so every calls to pp->getChar and pp->ungetChar ultimately call this->getch
and this->ungetch while adding overhead of virtual calls and vector::back.

b5c046e58b Front-end: Fix missing tessellation shader built-in qualifiers. 
The gl_in array has a special path due to context-specific
gl_MaxPatchVertices, making the code out of order for tagging built-ins.
This commit moves the tagging to the correct location.
This also fixes issue #80.

eb505e4262 Allow future keywords to be accessed as members in a struct. 
This fixes a bug where a token that could be a keyword in one version
is not a keyword in another version, but treated like a non-member after
a "." dereference.

6373574b13 Front-end: Fix: Cubemap arrays only use 3-component coord when accessed as an image. 
4 components are needed when used a texture, but not an image, which multiplies
layers and faces into the same coordinate.  This fixes it from using 4 everywhere,
to only using 4 for textures and 3 for images.

ba01ebd5ba Link-check fix: Don't include built-in variables in the fragment output ES rule: 
"No layout(location=) is required if there is only one output" should not count
built-in variables like gl_SampleMask.  This is fixed.
