Subject: [PATCH] build: Add missing math.h includes

Commit 0f786ce451297f8d26d41dc8492c10db08d8f87f added a math.h include
statement to libxfce4panel/xfce-panel-image.c to fix issue #833.
However, libm functions are used in more files than just
xfce-panel-image.c.

Therefore, add math.h include to other files that use math functions.
