Added love.graphics.getStats. It returns a table with performance-related graphics statistics. Currently it contains these fields:

Browse Source 
drawcalls: The number of internal draw calls made so far in the current frame.

canvasswitches: The number of times the active Canvas has been changed so far in the current frame.

texturememory: The approximate amount of video memory (in bytes) used by OpenGL textures created by Images, Canvases, and Fonts.

images: The number of active Image objects.

canvases: The number of active Canvas objects.

fonts: The number of active Font objects.
