All lines have to be of equal width, divisible by eight (a restriction imposed by the underlying SDL implementation). When used in an application, it should look as depicted in the next screenshot (the image is significantly zoomed in, obviously): Mouse cursor for the Kivy Paint app: a crosshair There is a caveat though. compile() function that switches between white and black. Detecting the affected versions of Pygame is impractical, so we'll just include the correctly working function in our code and won't call the potentially buggy version of the same function.

Fill() In Kivy, on the other hand, this pattern still just adds drawing instructions; it first renders all of the pre-existing primitives and then paints them over with a rectangle. This looks just about right (the canvas is visually empty) but does the wrong thing: # Same code as JavaScript above. This is wrong, don't do it! size) Just like a memory leak, this bug can go unnoticed for a long time, quietly accumulating rendering instructions and degrading performance. Thanks to powerful video cards found in today's devices, including smartphones, rendering is generally very fast.

We can also retool many web-development-oriented assets easily, reusing fonts, colors, and shapes from CSS frameworks, such as Bootstrap. And by all means take a look at Google's Material design principles—this isn't just a collection of design assets, but a complete field guide that allows us to achieve a consistent and good-looking UI without sacrificing the identity or "personality" of our application. This is, of course, only the beginning. Many features that were briefly discussed in this chapter will be explored more in-depth later in this book.
