2016-04-27	wimmel.frag: Define the required precisionHEAD master	Benjamin Franzke	1	-0/+2
	Or we get errors like: fragment shader info: 0:1(1): error: no precision specified this scope for type `vec2' 0:4(1): error: no precision specified this scope for type `vec2' 0:6(1): error: no precision specified this scope for type `vec4' 0:13(2): error: no precision specified this scope for type `float' 0:17(2): error: no precision specified this scope for type `vec4' 0:18(2): error: no precision specified this scope for type `vec4'
2012-03-24	wimmel_gl: Use GL_BGRA_EXT in readpixels	Benjamin Franzke	1	-1/+1
	That is the native format graphics cards use, so we reach a fastpath for the copy, which saves around 1s.
2012-03-21	wimmel_gl: Use luminance textures	Benjamin Franzke	1	-1/+2

2012-03-15	wimmel_gl: Use a second texture unit for search region	Benjamin Franzke	1	-1/+2
	Speeds up calulation from ~11s to ~10s.
2012-03-15	wimmel.frag: Rename search_rect to srect	Benjamin Franzke	1	-7/+6

2012-03-14	Revert "wimmel.frag: Discard fragment early if difference is to significant"	Benjamin Franzke	1	-6/+3
	This reverts commit 5bcbaab8ea90655c2496c8df029a9cb991dba0ce. This was 0.2seconds faster on r600g but 4 seconds slower on sandybridge.

2012-03-14	wimmel: Render to a fbo	Benjamin Franzke	1	-1/+1

2012-03-14	Add wimmel_gl prototype	Benjamin Franzke	1	-0/+27
	Uses a shader to search for matching subimages.
