pix = page.get_pixmap(matrix=matrix, clip=rect) recommend to modify function get_pixmap

Is your feature request related to a problem? Please describe.
When I used pix = page.get_pixmap(matrix=matrix, clip=rect), I found:
This function always performs the image cutting (clip) first, and then performs the matrix transformation, which may be in reverse order, should you perform the image transformation before performing the cutting?

The design has been chosen with due consideration: in this way only necessary data will submitted to any desired transformations, reducing memory requirements.

You can always create sub-pixmaps from a pixmap, so you can first transform and then extract a subset from the result.
