Elias Naur 14805af367 gesture,widget,f32: [API] use integer coordinates for gesture coordinates 
Most widget code operate in integer coordinates. This change makes
gesture pointer coordinates integer, to lessen the number of float32
to int conversions.

Elias Naur 1f11a5a17b f32,gpu,op/clip: add f32.Rectangle method for converting to image.Rectangle 
Creating an image.Rectangle from a f32.Rectangle is used by two packages in Gio
and about to be used for a third. Add a Round method to f32.Rectangle to avoid
duplicating the implementation.

The old renderer depends on the old behaviour of Union, so change that
reference to a copy.

Egon Elbre 24d6f3fb65 f32: optimize Affine2D 
encode/decode seem to introduce significant overhead. Inline them
manually. It'll make code harder to read, however the performance wins
are significant.

Elias Naur d82eb8fc66 layout,f32: add convenience functions for rectangles and points 
layout.FRect, layout.FPt for converting from integer to floating point,
useful for drawing operations.

f32.Pt is a shorthand that mirrors image.Pt.
