• Optimized findLSB and findMSB functions.
• Optimized matrix-vector multiple performance with Cuda #257, #258
• Reduced integer type redifinitions #233
• Rewrited of GTX_fast_trigonometry #264 #265
• Made types trivially copyable #263
• Removed in GLM tests
• Used std features within GLM without redeclaring
