Incomplete matrix swizzle #3

Closed Beuc closed 7 years ago

Beuc commented 7 years ago

Hi,

I noticed that the matrix swizzle is incomplete. For instance I wanted to use .xyw, which is missing, when converting a 3D transformation matrix to a 2D one.

    var mvp = ...
    var mvp2D = glm.mat3(mvp[0].xyw, mvp[1].xyw, mvp[3].xyw);

I had to manually expand it (see https://gitlab.com/wikibooks-opengl/modern-tutorials/blob/master/2d-webgl/sprites.html).
