[PD-dev] [GEM] new commits

[chris clepper]

The following was committed earlier tonight:

GemMan - added a variable to hold the calculated fps of the render

GemWinCreateMac - secondscreen now defaults to a minimum of 648x480

gemwin - now has an outlet for the fps, which is sent every time a 
'fps' message is sent to the gemwin

newWave - speed argument now accepts all positive float values and 
multiplies it by 0.001

polygon - can draw using all of the GL draw types

pix_background - grabs a single frame and compares all incoming 
frames to it.  pixels that are within a specified range are turned 
black.  this can be used to remove the background of a live video 
feed.

pix_blur - fixed a little crash when resizing buffers and using altivec

pix_duotone - changes the image to a two tones based on a threshold 
and user supplied colors

pix_roll - rolls or scrolls the image on the x or y axis

pix_texture - for YUV textures the memset is replaced with a for loop 
to black out the buffer

pix_texture2 - removed the memset when RECTANGLE textures are used

pix_threshold - now works with yuv

all of the pix_ objects above work with both RGB and YUV

jamie also finished up work on pix_filmDarwin and the performance is 
now much, much better.
