    Changed the behaviour of Clock.tick to use SDL_Delay instead of a busy

      is more consistent with what people think Clock.tick() will do.
      That is, not use 100% cpu to get more accurate timing.
    testsprite.py example, which is based off the testsprite.c in SDL
      shows the performance of sprites, and is a good test.
    Added gp2x package which contains some constants for the gp2x buttons.
      This will be where gp2x specific functionality will live.

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
