Glowmesh

This is a thin mesh abstraction for glow. Its very ooga booga style: simply implemented per common vertex type. For now XYZRGBA. The _build2d module is for 2d rendering, providing functionality for triangle, quad and polygon rendering (more to come like lines etc).

examples/triangle may serve as a starting point for OpenGL application development

Todo

• todo fix resizing on wayland if thats even possible lmao
• todo recycling handles
• todo rotozoom triangle with projection matrix... in accompanying matrix library xD
• add texture or think about what ive done wrt uvquad0. maybe gets a buffer as a texture or something like
• texture thing can bind screen buffers and shit

ISSUE - texture comes in as all 0. fix that then we can move on eg to gball but plus this will be ready

see if using old image loading code works...
