martinfouilleul	4e816a838b	[Clean canvas/shaders] ... - Simplified shader names, prefix embedded strings by "glsl_" - Extracted shader compilation in common function - Add shader version string and common structs in canvas code rather than in every shader file - Renamed zIndex with shapeIndex everywhere	2023-02-09 16:14:15 +01:00
martinfouilleul	4a8c77f023	- Move and Zoom perf_text example with the mouse ... - Reverted to using 4 bits of subpixel precision and computing cross products with 32 bits integers, for perf reasons - Fixed some confusion in tile array size vs number of elements (could still clean-up naming a bit though) - Fixed bug where triangles on the left or below canvas boundaries where bucketted to the first colum/row of tiles - Fixed bug in mouse button message handling (was always sending press on left button)	2023-02-09 13:09:41 +01:00
