BuddhaShader - First steps with OpenGL: A compute shader that renders a BuddhaBrot to an SSBO. Can also save the result to PNG for future viewing pleasure.

*	Back to full image size buffers, and range support in shader	Andreas Grois	2018-03-23	1	-18/+17

*	Initial benchmark support.	Andreas Grois	2018-03-21	1	-2/+12

*	Undo splitting of buffers in three. Makes buffer access much faster	Andreas Grois	2018-03-18	1	-2/+2
\| \| \| \| \|	Not kidding here. For the default parameters this increased the maximum pixel brightness in the image by a factor of 2.25. This has the drawback that the maximum possible image size got reduced, but hey, there's a command line switch to ignore all size limits ;-)
*	Add option to skip short orbits. Add option to print debug output.	Andreas Grois	2018-03-18	1	-1/+5

*	Adjust default workgroup sizes to better match recommended values.	Andreas Grois	2018-03-17	1	-5/+5

*	Fix endless loop in shader and make framerate adaptive	Andreas Grois	2018-03-15	1	-2/+2
\| \| \| \| \| \|	It seems forcing points outside the cardioid and bulb with a bad random generator can take really long... Also, now framerate adjusts based on time it takes to render frames.

The maximum buffer size limitation is rather strict on radeonsi, so I decided to split the buffer in three, effectively increasing the maximum image size by a factor of three. While doing so I realized that at least on radeonsi the reported maximum buffer size seems to be off. For this reason I added a new command line switch, that allows to ignore the maximum buffer size check. For those curious: radeonsi reports a maximum buffer size of 128 MB, but I had no problems when using three buffers of 1098 MB each.
