v0.4.1: vector update

• optimize non-optimized with SIMD vec4 operations with SSE/SSE2
• add one and zero helpers for vectors
• fix scale_as for zero length vector: now it it returns zero
• new functions for vec3 and vec4: (s suffix stands for scalar)
  • _mul: multiply two vector (replacement for _mulv)
  • _div: div two vector
  • _divs: div vector with scalar
  • adds: add scalar to each components of vec
  • subs: sub scalar from each components of vec
  • addadd, subadd, muladd, muladds helpers ( += )
• optimize rotate vec3 using matrix4, add same function for mat3
• add some tests for vectors
• update docs for new apis

and lots of improvements, bugfixes (and features) may not listed above!

v0.3.5

• clamp functions

v0.3.0: arm neon support, re-organise file/folder structure

• ARM Neon support for matrix multiplication
• re-organise file/folder structure;
  • remove cglm prefix from file names
  • separate vec4 operations into separate header
• add missing header documentations
• fix raw matrix multiplication
• supress warnings

v0.2.1: build: fix make install include path

• add removed functions as macro as DEPRECATED for compatibility
• fix build scripts

v0.2.0

• _dup (duplicate) is changed to _copy. For instance glm_vec_dup -> glm_vec_copy
• OpenGL related functions are dropped to make this lib platform/third-party independent
• build conf for windows
• add some vector operations
• add cmocka to unit tests
• optimizations
