don't call Len() when it can't change
...
updateData()'s loops checking gt.Len() turns out to have been costing
significant computation, not least because each call then in turn
called gt.vs.Stride().

Don't duplicate computations in gltriangles.go
...
The computation including a call to Stride() can't be optimized away
safely because the compiler can't tell that Stride() is effectively
constant, but we know it won't change so we can make a slice pointing
at that part of the array.
CPU time for updateData goes from 26.35% to 18.65% in my test case.

Simplify Matrix math, use 6-value affine matrixes.
...
It turns out that affine matrices are much simpler than the 3x3 matrices
they imply, and we can use this to dramatically streamline some code.
For a test program, this was about a 50% gain in frame rate just from
the cost of the applyMatrixAndMask calls in imdraw, which were calling
matrix.Project() many times. Simplifying matrix.Project, alone, got a
nearly 50% frame rate boost!
Also modify pixelgl's SetMatrix to copy the six values of a 3x2
Affine into the corresponding locations of a 3x3 matrix.
