Josip Miskovic 944a6029f0 Add mat4:targetAt and modify the mat4:lookAt 
lookAt() returns view matrix that can be used to transform the camera
perspective. target() returns model matrix that is used to change
model transform. Results are matrix inversions of one another. Now both
functions exist it is possible to use right one and avoid extra matrix
inversion.

bjorn 9bdceb0094 rm LOVR_INLINE; 
Just use the inline keyword which is C99.  Getting util.h out of
maf.h is nice.

It was only used when exporting functions for JavaScript.

fix mat4_lookAt translation offset 
need to dot with the axes to not have bizarre results.

bjornbytes 80a33c0544 mat4_multiply -> mat4_mul; 
quat_mul vs. mat4_multiply is inconsistent.  Going with mul over
multiply is consistent with vec3_sub and Lua's __mul metamethod.

Josip Miskovic ceaac78439 Fix NaN return from mat4 unpacking 
The caluclated angle is forced to PI if cos(angle) falls outside the
[-1, +1] range due to floating point precision error.

mcc d8abfcfae3 Remove mat4_transform_project, it not only duplicates mat4_transform, it is buggy 2020-04-05 19:51:37 -04:00

bjorn 723f5684cf Fix mat4_fov and desktop driver projection; 
OpenVR may need updating now, but at least we know what the correct
approach is now.

bjorn b35ebc15b6 rm LOVR_USE_SSE; 
It doesn't really improve performance on an average LÖVR app and
isn't worth the complexity.

mcc 8bfc8683db Patch maf.h so it can be included in C++ 
A C-only feature is used in one spot currently, which would be fine if maf.h were maf.c, but it's designed to be #included...

mcc 53270fbd76 mat4_transform_project in maf.h 
mat4_transform ignores the final row of the matrix, which normally contains scale data. This is fine for modelview matrices, which is all lovr currently uses mat4_transform for. However it fails if you ever use mat4_transform on a projection matrix.

mat4_transform_project takes the final row into account, so you can use it with projection matrices. This was useful in my fork and might be useful to have around in lovr someday later.

bjorn 22fe333150 Update refcounting (again); 
- Ref struct only stores refcount now and is more general.
- Proxy stores a hash of its type name instead of an enum.
- Variants store additional information instead of using a vtable.
- Remove the concept of superclasses from the API.
- Clean up some miscellaneous includes.
