Contains few fixes required for d3d12. These are mainly alignment issues that came up with HLSL. The matrix ordering for StoredBuffers and constant buffers in HLSL is not always the...

If no text is being displayed then gfx.Text.updatePipeline leaks memory when used in d3d12. There is a defer on encoder.release but that does not seem to be sufficient to release...

The glyph texture uses the alpha channel to anti-alias fonts. This information is not correctly used in the text shader. ``` return vec4(color.rgb * c.a, color.a); ``` where c.a is...

Mach includes a collection of function to determine if various 2D primitives collides. (this is related to https://github.com/hexops/mach/issues/1084) The primitives in the collision module are: * Point * Line (a...

* Added function to compute contacts between polygons and circles. * Added documentation for existing functions. * Fixed a bug in Line.collideLine. * Added more unit tests. Related to #1243...
