Christoph Oelckers	cf30f5560b	- upgraded the polymost fragment shader to GLSL 3.3 as well, removing all legacy features from it. ... The only compatibility mode feature left is the main drawer function using glBegin/glEnd but changing that is not as urgent as the rest. This also cleans up the fog application and adds the exponential fog mode again that somehow got lost over time.	2019-10-06 12:42:35 +02:00
Christoph Oelckers	71d132b470	- use explicitly declared matrix uniforms. ... The builtin matrices are no longer available in modern GLSL, preventing an upgrade of the shader. Also perform better reporting of shader compilation errors.	2019-10-06 10:19:51 +02:00
Christoph Oelckers	3c193bb243	- moved the animvpx shader to the backend code. ... This removes the final access to OpenGL from the rest of the source, with the exception of the glFinish call in the swap code.	2019-10-05 13:38:02 +02:00
Christoph Oelckers	b83349fe6b	- moved the surface shader to the backend and the shader source to the resource file.	2019-10-05 13:09:15 +02:00
Christoph Oelckers	bd4e4834e3	- moved the main shader and its entire uniform maintenance into the backend.	2019-10-05 12:28:08 +02:00
